SIS Mirage 3 671MX vs NVIDIA GeForce G 205M

The NVIDIA GeForce G205M or G 205M is an integrated (onboard) graphics card for laptops. Technically its a renamed GeForce 9400M G (also used in ION 1 Netbooks) and not related to the newer G210M or G310M.

The performance of the G205M is comparable to current entry level GPUs with dedicated graphics memory (like the GeForce 9300M GS). The newer GeForce G305M is still noticeable faster. Older games like Doom 3 or less demanding games should still run fluently on the G205. See our GeForce 9400M G page for detailed benchmarks.

Because of the shared memory (the memory is reserved from the main memory), the graphics adapter performs significantly better with DDR3 main memory than with DDR2 (up to 33% more performance).

The current consumption of the mGPU is with a maximum of 12 Watt TDP (for the whole chipset (north- and southbridge are integrated) on par with the current Intel GMA X4500MHD (Centrino 2). The newer GMA HD in the Core CPUs should use less power (at a similar performance level as the G205M but with a worse driver support).

As the 9500M G, the G205M features 16 stream processors that do the work of the former dedicated pixel- and vertex-shaders. The unified shaders of Nvidia are 1-dimensional (AMD has 5-dimensional shaders which leads to the higher number of shaders).

The MCP79MX/C (codename of the GeForce 9400M/G 205M) can help the CPU in decoding HD videos. It features the PureVideo HD engine (VP3 video processor). Furthermore, the chip can be programmed using CUDA and can accellerate some operations in Photoshop CS4.
