The MSI N250 card is based upon NVIDIA's G92 chip which has been used in numerous cards over the last two years starting with the GeForce 8800GT in late 2007. The chip has been shrunk down to 55 nm process when the 8800GT was at 65nm. The card has the same number of transistors; ROPs texture units and memory bus as the 9800GTX+ which was released early last year. In fact, GPUZ reports that this card was manufactured in June of 2008.
MSI differentiates their card by having higher clock speeds in all three domains Core, Shader, and memory than the NVIDIA reference card. 760MHz for the core clock is slightly higher than the 738MHz on the reference card. Also, the Shader clock of 1835Mhz is higher than the reference clock. This card has 1GB of DDR3 memory clocked at 1135 or 2270MHz effective giving the card a maximum memory bandwidth of 72.64GB/second.
DirectX 11 will be here later this year or early next year with support for Compute Shaders, Hull Shaders, Pixel Shader 5.0 and more with the release of Windows 7, the replacement for Vista. That will be the next major insertion point for graphics cards and NVIDIA will likely support it. For now, NVIDIA has stuck to DirectX 10.0 skipping DirectX 10.1 altogether. Pixel Shader 4.0, Vertex Shader 4.0, the second generation Unified Shader Architecture and 128 Stream Processors are supported on the GTS 250.
The card has specialized cooling with four 6mm heatpipes, a huge heatsink area, a low-noise fan, and award winning thermal technology. The solution is very cool running with silent operation during most tasks. MSI uses Solid Capacitors like on motherboards to prevent leakage of capacitors that get broken off. Dual CoreCell is their component status hardware monitoring utility that integrates multiple integrated circuits. Their overclocking utility is called DOT Express or Dynamic Overclocking Technology.
