    Default Ati Radeon 4850

    If anyone is intrested in buying a 4850 (Gigabyte,Sapphire,powercolor) for ~22,000tk

    4850 Specs:
    Direct X 10.1
    Shader MOdel 4.1
    800 SP
    HDMI 7.1

    Feature wise and performance wise its better than a 9800GTX (which is ~30,000tk in BD)
    P.M. me

    and the GTX280 is still the fastest card, even tho its stupidly expensive. For people who dont care tho, they can still go nvidia. i myself am an amd fan tho, so its great to see amd/ati making a comeback

    Shader MOdel 4.1
    800 SP
    HDMI 7.1

    Feature wise and performance wise its better than a 9800GTX (which is ~30,000tk in BD)
    P.M. me
    is the 4850 with warranty?

    The computing part of the R600 and RV670 chips consisted of 64 universal units each of which had five ALUs, a flow control unit, and an array of general-purpose registers. Four out of the five ALUs were rather simple, capable of executing one FP MAD instruction. And the fifth ALU was complex, capable of processing such instructions as SIN, COS, LOG, EXP, etc. In fact, each execution unit was a processor with a five-stage pipeline.

    Theoretically, the GPU contained 320 execution units but this was only true when all the 64 pipelines were loaded, which was not always the case. In 3D applications many operations depend on the results of previous operations, so it is hard to keep the pipeline loaded always. Application-specific optimizations in the Catalyst driver were required for that but it is often impossible to get access to the game code until it is officially released.

    As the consequence, the ATI Radeon HD architecture often found itself using but one ALU in each execution unit and lagging behind the competing G80/G92-based solutions from Nvidia. The latter not only had more independent execution modules but also worked at higher clock rates. Creating the RV770, the ATI developers solved the problem of the potential inefficiency of the superscalar architecture in the most direct way – by increasing the number of execution modules from 64 to 160. Of course, it means there are more transistors in the core, but the 55nm tech process helped keep the size of the core within reasonable limits.

    The architecture of the units has not changed much. Each of them still consists of five ALUs, one flow control unit, and a few general-purpose registers.



    ATI claims the execution units are now 40% more efficient, but the brutal increase in number (from 64 to 160) is already enough to make the Radeon HD 4800 competitive even under unfavorable conditions. That’s not all, though. As we mentioned above, there are more global changes on the core topology level. With the ring topology retained partially, the placement of the functional subunits has been optimized. The RV770’s execution subunits have been joined into 10 SIMD cores (the previous GPU had 4 such cores) with 16 modules (80 ALUs) in each:



    Each execution core has a dedicated control logic, 4 TMUs and L1 cache. The cores can communicate locally as well as globally.

    Note that the ratio of computing and texture-mapping units has remained the same at 4 to 1. ATI thinks it optimal. You may argue the point but the argument makes no sense for the RV770 because, unlike its processor, this GPU shouldn’t feel a lack of computing or texture-mapping power. Of course, the new chip offers full support for DirectX 10.1.
    U can read the Whole article here -> Ati 4800 graphics Architecture

    The Ati 4800 series have more potential. Optimized drivers will give more FPS in games!

    Hey maybe 4870x2 would beat up GTX280 and 4870x2 might be priced around $500.

    Is there any benchmarks or sth like that about 4870x2 ?

    4870 just falls behind with 8 fps while it was compared to 9800gx2 while 4870 is not crossfired

    and i personally own a 4850 and it rokz
    and i will sell it after 3 months coz i m buying 4870 frm bangkok baby
