    Thumbs up Radeon HD 4000 Series in June With DDR 5 !!!

    German site called HARTWARE.NET is to be believed, AMD’s next generation of Radeon graphics cards could be released as early as June this year. According to the site, an AMD roadmap it has managed to acquire shows seven upcoming cards, the Radeon HD 4450, Radeon HD 4470, Radeon HD 4650, Radeon HD 4670, Radeon HD 4850, Radeon HD 4870, and Radeon HD 4870 X2. The 4400 cards will apparently feature 40 stream processors, the 4600 cards will have 240 and the 4800 cards will have 480 (with the X2 featuring 960 overall, 480 on each core). There is no firm indication of clock speeds, but the 4600 and 4800 cards are expected to run somewhere between 800MHz and 1050MHz depending on the model, ranging from 128MB of DDR2 to 1GB of GDDR5 memory. However, there are no details of which cards will be released when, just that the initial launch could be sometime in June. Remember that this information might not be completely reliable and shouldn’t be interpreted as firm facts.

    The R700 series is supposed to b 2 times faster than the R600!

    I don't like Nvidias new naming scheme. Like the 9800 x2, slapping together 2 current generation chips and naming it like a new generation chip. Some will fall for it as many think bigger number means better performance, but i am not.
    U can say it for the Ati 3000 series too, but at least it has a new feature... supporting Directx10.1 and some minor changes.

    "The product launch will be significant not just because of the availability of chips, but also because of the fact that AMD/ATI is returning to a true six-month refresh cycle of its graphics products. Looking back, the 2900/3800 series was not really a six-month refresh, since the 2900XT was eight months late. The Radeon 3800 series was launched in November of 2007 and since the Radeon 4800 is pretty much set for a May 2008 launch (cards went into production in March), the ATI team has returned to its traditional cycle. There is a good chance that the acquisition troubles have been digested and new products will be surfacing in a more predictable fashion from now on.

    Specifications: 480 stream processors, 800+ million transistors

    Let’s have a look at the general specifications of the Radeon 4800 series, which is based on the RV770 graphics processor. The new GPU has 480 stream processors or shader units (96+384), 32 Texture units (up from 16), 16 ROP (same as 2900/3800), a 256-bit memory controller and native GDDR3/4/5 support (expect GDDR3 and GDDR5 memory versions of RV770 cards).

    The transistor count has jumped from 666 million in the RV670 to more than 800 million transistors in the RV770.

    The manufacturing process has been carried over: TSMC is producing the GPUs in 55 nm (the process itself is called 55GC).

    The Radeon 3800 series had a serious flaw called texture low fill-rate, which was addressed by ATI with an increased number of TMUs (Texture Memory Unit) from 16 to 32. The specifications indicate that 16 TMUs can address 80 textures on the fly, which means that 32 units should be able to fetch 160 in the RV770: This should allow the new GPU to catch up with NVIDIA’s G92 design. However, the G92 has 64 TMUs that were enabled gradually (some SKUs shipped with 56), resulting in a fill-rate performance that beat the original 8800GTX and Ultra models.

    ATI’s RV770 will be rated at a fill rate of 20.8-27.2 GTexel/s (excluding X2 version), which is on the lower end of the GeForce 9 series (9600 GT: 20.8; 9800 GTX: 43.2 9800 GX2: 76.8).

    New for the 4800 series is AMD’s decision to split the clock of the GPU and shaders, following a move that NVIDIA made with the GeForce 8800: Back then, the shaders were clocked at 1.35 GHz, while the rest of the chip ticked at 575 MHz.

    The Radeon 4850 will debut with a GPU clocked at 650 MHz, while the shader array will be clocked 850 MHz. The 4870 has an 850 MHz core and a 1050 MHz shader clock. The fill-rate is closely tied to the GPU clock: The 4850 sports a fill-rate of 20.8 GTexel/s (32 TMU x 0.65 GHz), while the 4870 achieves a 27.2 GTexel/s (32 TMU x 0.85 GHz) performance.

    The RV770 GPU is equipped with a 256-bit memory controller (512-bit for the Radeon 4870 X2: The R700 represents just two RV770 GPUs slapped together). 4850 GDDR3 models will come with 256 MB or 512MB of GDDR3 memory, clocked at 1.14 GHz (2.29 GTransfer/s), resulting in a memory bandwidth of 73.2 GB/s. 4850 GDDR5 versions integrate 512 MB of GDDR5 memory clocked at 1.73 GHz (3.46 GT/s), supporting a bandwidth of 110.5 GB/s. 4870 GDDR5 models will get 1 GB of memory clocked at 1.94 GHz (3.87 GT/s), achieving a maximum bandwidth of 123.8 GB/s.

    Flagship dual-GPU 4870 X2 cards will include 2048 GB of GDDR5 memory clocked at 1.73 GHz. The Radeon HD 4870 X2 will be introduced at a later date (and could see spec revisions).

    You may be wondering why ATI decided to go with "odd clocks" for the video memory part and the answer may surprise you: According to our sources, AMD is no longer clocking the cards towards performance, but towards power efficiency instead. This happened first with the Radeon 2900XT (which was bleeding lots of current) and continued with the 3800 series.

    Overclockers should have no problem reaching the magic 4 GHz mark for the GDDR5 memory (1.94 to 2.0 GHz), but that, of course, would break the sub-150 watt thermal-envelope these cards were designed for. More than ever before we can envision AMD and add-in-board vendors offering a “Radeon HD 4870 TDP - Saves you $$$ on Electricity Bills!" or a "4870 Lots of Horsepower and Power Hungry" edition of these cards.

    The 4850 in fact is in a 110 watt power envelope (the 4850 256MB GDDR3 is a sub-100 watt card). There is, by the way, a big difference in power consumption between GDDR3 and GDDR5 versions. 512MB GDDR5 memory will consume 34.5% less power than a model with 512MB of GDDR3 memory.

    As you can guess, a 110 watt power envelope means that 4850 boards will have a single-slot cooler, while the 150 watt part (4870) should be available as single-slot part as well (from at least one partner, 1-slot vapor chamber part). Most of manufacturers will, however, offer dual-slot cooling for the 4870.

    4870 X2 is an interesting version. AMD did not send out any specs to its partners and it is expected the board will be a bit more than just a 3870 X2 two RV770 GPUs. ATI is said to be making some changes, most notably in the PCI Express department (3870 X2 is actually a PCIe 1.1 part). The product will keep the aggressive pricing in place, and, according to our sources, will scale much better than 3870 X2.

    The 4850 256MB GDDR3 version will arrive as the successor of the 3850 256MB with a price in the sub-$200 range. The 4850 512MB GDDR3 should retail for $229, the 4850 512MB GDDR5 will set you back about $249-269. The big daddy, the 1GB GDDR5 powered 4870 will retail between $329-349.

    When it will become available the 4870 X2 will hit the market for $499.

    Our sources indicate that the launch is only weeks away, so expect your usual hardware sites to feature dozens of reviews of 4850 and 4870 with GDDR5 memory, since this memory type will be a hot topic in months to come."

    @giddy soul: those benchmarks arent true, it has been proved in various forums. However, it will certainly be competitive with the 9800GX2, cant surpass it tho, the 4870X2 should do that easily

    To get a more closer approximation of the relative performance of the 4870, without going into more details(which i will happily give if you ask for it), here are the approximations

    10% higher core clock than HD 3870
    24% higher shader clock than HD 3870
    70% more memory bandwidth than HD 3870
    50% more stream processor than HD 3870
    100% more TMUs than HD3870
    Same ROPs as the HD 3870

    which should equal roughly 2X the shader performance. 2X the Texture mapping performance. 2X the memory throughput. 1.1X the pixel mapping performance. Rumors say that per flop performance increased as well, as the TMU architecture was broken on the R600 family. Overall, the card should be 2X faster than the 3870

    Recent news show the radeon 4800 series actually have 800SP! and It can possible beat 9800gx2 in many benchmarks!

    AMD Preps Radeon 4850 Launch for June 25

    Hot on the heels of NVIDIA's GTX 200 family launch, AMD will introduce its 55nm RV770-based Radeon 4850 next week.

    The Radeon 4850 features a 625 MHz core clock and GDDR3 clock in excess of 2000MHz. Corporate documentation explains that the 480 stream processors on the RV770 processor offer considerable enhancements over the 320 stream processors found in the RV670 core, though AMD memos reveal little about how this is accomplished.

    The RV770 includes all the bells and whistles of the RV670 launched in November 2007: Shader Model 4.0, OpenGL 2.0, and DirectX 10.1. The only major extension addition appears to be the addition of "Game Physics processing" -- indicating a potential platform for AMD's recent partnership with Havok.

    The new Radeon lacks GDDR5 memory, promised by an AMD announcement just weeks ago. Although the RV770 does support GDDR5 memory, this initial launch consists exclusively of GDDR3 components. AMD documentation hints at the launch of a Radeon 4870 later this summer, but it offered no comment on when it will eventually ship a GDDR5 product.

    If Radeon 4850 sounds familiar, that's because it is. The RV770-based FireStream 9250, just announced a few days ago, broke the 1 teraflops barrier using the same graphics core. However, this paper-launched workstation card will retail for more than $900 when it finally hits store shelves. The mainstream Radeon 4850 offerings will ship and launch on the same day next week.

    AMD partners claim the new card will not compete against the $600 GTX 200 just announced yesterday. Instead, AMD pits the Radeon 4850 against the recently re-priced NVIDIA GeForce 9800 GTX. Distributors claim the 4850 will see prices as low as $199 at launch -- well under the $299 MSRP for GeForce 9800 GTX. More expensive versions of RV770 will feature HDMI, audio pass-through and possibly the fabled Qimonda GDDR5 memory.

    Specifications from Diamond Multimedia marketing material claim the new Radeon will require a 450 Watt power supply for single card support; or 550 Watt power for CrossFire mode.
    Source Daily tech.


    The way things are shaping up the 4870x2 might indeed trump the GTX280.
    It's a 200 video card said to be as fast as the 9800GTX, which currently costs about 300. I'd say that's pretty good.
    It appears to me AMD was right when they said the era of the monolithic chip is over. And Nvidia looks wrong. In raw performance AMD slides claim 2.8X more performance (flops) per die area than Nvidia. And 2.25X per watt.

Looking back, the 2900/3800 series was not really a six-month refresh, since the 2900XT was eight months late. The Radeon 3800 series was launched in November of 2007 and since the Radeon 4800 is pretty much set for a May 2008 launch (cards went into production in March), the ATI team has returned to its traditional cycle. There is a good chance that the acquisition troubles have been digested and new products will be surfacing in a more predictable fashion from now on.

    Specifications: 480 stream processors, 800+ million transistors

    Let’s have a look at the general specifications of the Radeon 4800 series, which is based on the RV770 graphics processor. The new GPU has 480 stream processors or shader units (96+384), 32 Texture units (up from 16), 16 ROP (same as 2900/3800), a 256-bit memory controller and native GDDR3/4/5 support (expect GDDR3 and GDDR5 memory versions of RV770 cards).

    The transistor count has jumped from 666 million in the RV670 to more than 800 million transistors in the RV770.

    The manufacturing process has been carried over: TSMC is producing the GPUs in 55 nm (the process itself is called 55GC).

    The Radeon 3800 series had a serious flaw called texture low fill-rate, which was addressed by ATI with an increased number of TMUs (Texture Memory Unit) from 16 to 32. The specifications indicate that 16 TMUs can address 80 textures on the fly, which means that 32 units should be able to fetch 160 in the RV770: This should allow the new GPU to catch up with NVIDIA’s G92 design. However, the G92 has 64 TMUs that were enabled gradually (some SKUs shipped with 56), resulting in a fill-rate performance that beat the original 8800GTX and Ultra models.

    ATI’s RV770 will be rated at a fill rate of 20.8-27.2 GTexel/s (excluding X2 version), which is on the lower end of the GeForce 9 series (9600 GT: 20.8; 9800 GTX: 43.2 9800 GX2: 76.8).

    New for the 4800 series is AMD’s decision to split the clock of the GPU and shaders, following a move that NVIDIA made with the GeForce 8800: Back then, the shaders were clocked at 1.35 GHz, while the rest of the chip ticked at 575 MHz.

    The Radeon 4850 will debut with a GPU clocked at 650 MHz, while the shader array will be clocked 850 MHz. The 4870 has an 850 MHz core and a 1050 MHz shader clock. The fill-rate is closely tied to the GPU clock: The 4850 sports a fill-rate of 20.8 GTexel/s (32 TMU x 0.65 GHz), while the 4870 achieves a 27.2 GTexel/s (32 TMU x 0.85 GHz) performance.

    The RV770 GPU is equipped with a 256-bit memory controller (512-bit for the Radeon 4870 X2: The R700 represents just two RV770 GPUs slapped together). 4850 GDDR3 models will come with 256 MB or 512MB of GDDR3 memory, clocked at 1.14 GHz (2.29 GTransfer/s), resulting in a memory bandwidth of 73.2 GB/s. 4850 GDDR5 versions integrate 512 MB of GDDR5 memory clocked at 1.73 GHz (3.46 GT/s), supporting a bandwidth of 110.5 GB/s. 4870 GDDR5 models will get 1 GB of memory clocked at 1.94 GHz (3.87 GT/s), achieving a maximum bandwidth of 123.8 GB/s.

    Flagship dual-GPU 4870 X2 cards will include 2048 GB of GDDR5 memory clocked at 1.73 GHz. The Radeon HD 4870 X2 will be introduced at a later date (and could see spec revisions).

    You may be wondering why ATI decided to go with "odd clocks" for the video memory part and the answer may surprise you: According to our sources, AMD is no longer clocking the cards towards performance, but towards power efficiency instead. This happened first with the Radeon 2900XT (which was bleeding lots of current) and continued with the 3800 series.

    Overclockers should have no problem reaching the magic 4 GHz mark for the GDDR5 memory (1.94 to 2.0 GHz), but that, of course, would break the sub-150 watt thermal-envelope these cards were designed for. More than ever before we can envision AMD and add-in-board vendors offering a “Radeon HD 4870 TDP - Saves you $$$ on Electricity Bills!" or a "4870 Lots of Horsepower and Power Hungry" edition of these cards.

    The 4850 in fact is in a 110 watt power envelope (the 4850 256MB GDDR3 is a sub-100 watt card). There is, by the way, a big difference in power consumption between GDDR3 and GDDR5 versions. 512MB GDDR5 memory will consume 34.5% less power than a model with 512MB of GDDR3 memory.

    As you can guess, a 110 watt power envelope means that 4850 boards will have a single-slot cooler, while the 150 watt part (4870) should be available as single-slot part as well (from at least one partner, 1-slot vapor chamber part). Most of manufacturers will, however, offer dual-slot cooling for the 4870.

    4870 X2 is an interesting version. AMD did not send out any specs to its partners and it is expected the board will be a bit more than just a 3870 X2 two RV770 GPUs. ATI is said to be making some changes, most notably in the PCI Express department (3870 X2 is actually a PCIe 1.1 part). The product will keep the aggressive pricing in place, and, according to our sources, will scale much better than 3870 X2.

    The 4850 256MB GDDR3 version will arrive as the successor of the 3850 256MB with a price in the sub-$200 range. The 4850 512MB GDDR3 should retail for $229, the 4850 512MB GDDR5 will set you back about $249-269. The big daddy, the 1GB GDDR5 powered 4870 will retail between $329-349.

    When it will become available the 4870 X2 will hit the market for $499.

    Our sources indicate that the launch is only weeks away, so expect your usual hardware sites to feature dozens of reviews of 4850 and 4870 with GDDR5 memory, since this memory type will be a hot topic in months to come."

    To get a more closer approximation of the relative performance of the 4870, without going into more details(which i will happily give if you ask for it), here are the approximations

    10% higher core clock than HD 3870
    24% higher shader clock than HD 3870
    70% more memory bandwidth than HD 3870
    50% more stream processor than HD 3870
    100% more TMUs than HD3870
    Same ROPs as the HD 3870

    which should equal roughly 2X the shader performance. 2X the Texture mapping performance. 2X the memory throughput. 1.1X the pixel mapping performance. Rumors say that per flop performance increased as well, as the TMU architecture was broken on the R600 family. Overall, the card should be 2X faster than the 3870

    The way things are shaping up the 4870x2 might indeed trump the GTX280.
    It's a 200 video card said to be as fast as the 9800GTX, which currently costs about 300. I'd say that's pretty good.
    It appears to me AMD was right when they said the era of the monolithic chip is over. And Nvidia looks wrong. In raw performance AMD slides claim 2.8X more performance (flops) per die area than Nvidia. And 2.25X per watt.
