NVIDIA's unveils its newest $50 entry level DX9 graphics card
NVIDIA today announced its latest entry-level graphics offering, the
GeForce 7200 GS
GeForce 7200 GS
delivers Vista Premium Ready graphics performance at a low $50 price point. NVIDIA touts full support for DirectX 9.0, shader model 3.0 and high dynamic-range with the entry-level GeForce 7200 GS.
“Windows Vista, which benefits greatly from additional 3D performance, is gaining market share and mainstream applications such as Microsoft Maps, Google Picasso and iTunes are also starting to take advantage of 3D graphics,” Ujesh Desai, general manager of desktop GPUs, said. “By making a small investment in graphics performance, customers buying Vista PCs can go from an underwhelming experience to one that delivers exceptional performance and features.”
NVIDIA has severely crippled the
graphics core compared to its GeForce 7300-series, which uses the same core. The GeForce 7200 GS makes do with half the pipelines as the
GeForce 7300 GS
. This brings the total pixel pipelines to two, each with one texture unit. NVIDIA claims the GeForce 7200 GS delivers graphics performance that is 50% faster than integrated graphics solution. Strangely, AMD’s
690G integrated graphics chipset
features four pixel pipelines, each with one texture unit.
PureVideo video processing is also supported; however, NVIDIA is unclear if the GeForce 7200 GS supports
for high-definition video decoding acceleration.
Add-in board manufacturers are free to equip
GeForce 7200 GS
graphics cards with 128MB or 256MB of DDR2 memory. NVIDIA recommends 800 MHz for GeForce 7200 GS graphics cards. The DDR2-800 memory attaches to the GPU via a 64-bit memory interface. NVIDIA clocks the GeForce 7200 GS GPU at 450 MHz.
GeForce 7200 GS based graphics cards will be available to OEMs, system builders and retail. NVIDIA add-in board partners with GeForce 7200 GS products include Albatron, ASUS, Biostar, ECS, EVGA, Foxconn, Galazy, Gigabyte, Innovision, Leadtek, MSI, Palit, Point of View, PNY Technology, SPARKLE, XFX, Zogis and Zotac.

This 7200GS will be considerably faster than any GeForce 2 series card.
Yes the GeForce 2 Ultra had 4x2 TMUs clocked at 250MHz so had a theoretical peak texel fillrate of 2000 million/sec, whereas the 7200GS only has 2x1 TMUs clocked at 450MHz so has a peak texel fillrate of only 900 million/sec.
There is more to graphics cards than fillrate however, and the entire GeForce 2 series was extremely memory-bandwidth starved meaning they never achieved anything like their theoretical peak fillrate in real world situations. A good example of this is that the GeForce 4 MX440 (the GeForce 4 MX series being essentially a highly optimied GeForce 2 MX core, especially in the memory-controller) had only 2x2 TMUs clocked at 270MHz giving a peak texel fillrate of 1080 million/sec, yet it generally outperformed the GeForce 2 Ultra which had nearly twice the fillrate
more memory bandwidth (7.4GB/s vs 6.4GB/s).
Now if you were to compare the 7200GS with a GeForce 4 Ti4200 which also has a texel fillrate of 2000 million/sec like the GeForce 2 Ultra (both have 4x2 TMU clocked at 250MHz) but had a much more efficient memory-controller so it wasn't bandwidth starved (it also had slightly more memory-bandwidth than the GF2 Ultra though that is less important), it would probably be a different story as the Ti4200 might well be able to beat the 7200GS in DirectX 7 generation games. In DirectX 8 games using PS1.1, the 7200GS would probably be faster than a Ti4200 however due to the much higher core-clock and superior design of the 7200GS making up for having only half as many shaders. That's my best guess anyway.
The GeForce 4 MX filled a gap in nVidia's range between the very cheap GeForce 2 MX and the much more expensive GeForce 4 Ti. It may not have had pixel-shaders which was a shame but it kept the price down which was the intention, and was very good at what it could do and was quite rightly very successful. The 7200GS is also aimed at a very low price point, probably people who have bought Vista Home Premium and need a graphics-upgrade to use the Aero interface but don't want to spend more than they have to. They don't need a $500 card with 128 shaders clocked as high as possible; a $50 card with 2 PS3.0 shaders and stable drivers will satisfy their Vista requirements fine.
