![]() Support is available for Microsoft Windows at release, for Linux with Catalyst 8.10. The SIP block UVD 2.0-2.2 implemented on the dies of all Radeon HD 4000 Series Desktop gpus, 48xx series is using uvd 2.0, 47xx-46xx-45xx-43xx series is using uvd 2.2. The internal ring bus from the R520 and R600 has been replaced by the combination of a crossbar and an internal hub. RV770 features a 256-bit memory controller and is the first GPU to support GDDR5 memory, which runs at 900 MHz giving an effective transfer rate of 3.6 GHz and memory bandwidth of up to 115 GB/s. The RV770 also has 10 texture units, each of which can handle 4 addresses, 16 FP32 samples, and 4 FP32 filtering functions per clock cycle. The RV770 retains the R600's 4 Quad ROP cluster count, however, they are faster and now have dedicated hardware-based AA resolve in addition to the shader-based resolve of the R600 architecture. The RV770 extends the R600's unified shader architecture by increasing the stream processing unit count to 800 units (up from 320 units in the R600), which are grouped into 10 SIMD cores composed of 16 shader cores containing 4 FP MADD/DP ALUs and 1 MADD/transcendental ALU. All products implement TeraScale 1 microarchitecture. That's in line with Nvidia's PCIe slotted device that eats up about 160 watts.ĪMD plans to ship the FireStream 9250 and accompanying development kit in Q3 for $999.This article is about all products under the brand "Radeon HD 4000 Series". It's power consumption is about the same as its predecessor, demanding less than 150 watts and a power efficiency rate of eight gigaflops per watt. The 9250 fits in a single PCI slot, making it compatible with most desktops, workstations, and larger servers. The 9250 includes double-precision floating point hardware performing at more than 200 gigaflops. The FireStream 9250 comes with 1GB of GDDR3 (Graphics Double Data Rate 3) memory - which is actually half of what was previously offered in the FireStream 9170. Nvidia is similarly rolling out its 240-core Tesla-10 Series GPGPU chip that's also capable of 1 Teraflop of computational muscle. The FireStream 9250 is capable of 1 teraflop for single precision calculations, or 1 trillion floating-point operations per second. ![]() They promise massive speed improvements over a CPU in mathematical workloads of the scientific, educational and high performance computing variety.ĪMD claims developers are reporting up to a 55x performance increase on financial analysis codes as compared to using a CPU alone.ĪMD's new card succeeds the FireStream 9170, released last November and capable of 500 gigaflops for single precision performance. ![]() Instead of handling gaming or graphics operatins, GPGPUs are built to crunch hundreds of parallel calculations per clock cycle. The vendors will also exchange blows for the hearts and wallets of your friendly neighborhood medical imagers, seismic modelers, and computational fluid dynamicists.ĪMD is refreshing the FireStream processor line with a new general purpose GPU (GPGPU) that boasts more than one teraflop of processing power. The latest round of graphics card dueling between AMD and Nvidia isn't just over high-end gamers.
