Clearly defined pipelines - NVIDIA has shrouded much of NV31вЂ™s internal architecture in mystery, but they have revealed that NV31 has four pixel pipelines, each of which has a single texturing unit.Both companiesвЂ™ compromises sacrifice some precision for performance which is a better choice depends on real-world performance and image quality. ATI, by comparison, splits the difference and offers only 96-bit floating-point precision with the R300-series chipsвЂ™ pixel shaders, although the rest of the graphics pipeline offers a range of datatypes, including 64-bit and 128-bit floating-point formats. NVIDIA claims developers can be more efficient by defining their variables for the datatypes they need, mixing 64-bit and 128-bit processing as required. Of course, programs using 64-bit datatypes run faster than those with 128-bit datatypes. Like NV30 and NV34, NV31 supports 64- and 128-bit floating-point precision in its pixel shaders. In fact, NVIDIA takes things a few steps further by supporting longer pixel shader program lengths than called for by the pixel shader 2.0 spec. Pixel and vertex shader versions 2.0 - The key selling point of the NV31 graphics chip, and indeed of NVIDIAвЂ™s entire GeForce FX line, is support for DirectX 9вЂ™s pixel and vertex shader versions 2.0.IвЂ™ll just be highlighting NV31вЂ™s more important features here, but a more detailed analysis of NV31вЂ™s feature set and how it compares with NV30 and NV34 can be found in my preview of the GeForce FX 5600. As its name implies, the Asylum GeForce FX 5600 256MB packs 256MB of memory, but the card also has a few other tricks up its sleeve.Д«efore we consider BFG TechnologiesвЂ™ implementation of the GeForce FX 5600, itвЂ™s worth taking a moment to go over some of the key capabilities of NVIDIAвЂ™s NV31 graphics chip. Today weвЂ™ll be looking at NV31 as implemented in BFG TechnologiesвЂ™ Asylum GeForce FX 5600 256MB card. Like other members of the GeForce FX family, the GeForce FX 5600 is dressed up with enough DirectX 9 goodies to give users a вЂњcinematicвЂќ experience, although features alone donвЂ™t guarantee performance. Powered by NVIDIAвЂ™s NV31 graphics chip, the GeForce FX 5600 is a mid-range graphics card aimed at ATIвЂ™s Radeon 95 lines. For enthusiasts, however, the GeForce FX 5600 may be the most interesting card in the GeForce FX line. The GeForce FX 5800 Ultra is a noisy alternative to ATIвЂ™s Radeon 9800 Pro, and the GeForce FX 5200 is a slower performer in real-world games and applications than the Radeon 9000 Pro. Its price at launch was 149 US Dollars.T HUS FAR, the performance of NVIDIAвЂ™s GeForce FX line has left something to be desired. The card measures 171 mm in length, and features a single-slot cooling solution. GeForce FX 5200 Ultra is connected to the rest of the system using an AGP 8x interface. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. The GPU is operating at a frequency of 325 MHz, memory is running at 325 MHz.Д«eing a single-slot card, the NVIDIA GeForce FX 5200 Ultra draws power from 1x Molex power connector, with power draw not exactly known. NVIDIA has paired 128 MB DDR memory with the GeForce FX 5200 Ultra, which are connected using a 128-bit memory interface. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). It features 4 pixel shaders and 2 vertex shaders, 4 texture mapping units, and 4 ROPs. The NV34 graphics processor is an average sized chip with a die area of 124 mmВІ and 45 million transistors. Since GeForce FX 5200 Ultra does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. Built on the 150 nm process, and based on the NV34 graphics processor, in its 5200 Ultra variant, the card supports DirectX 9.0a. The GeForce FX 5200 Ultra was a mid-range graphics card by NVIDIA, launched on March 6th, 2003.
