NVIDIA GeForce G 205M vs NVIDIA GeForce G210M
NVIDIA GeForce G 205M► remove
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.

The Nividia GeForce G210M or G 210 M is a DirectX 10.1 graphics adapter for notebooks based on the GT218 core. As its predecessor, it features 16 shaders but the clock rates have been greatly increased and also the shaders were improved (different core). Because of the 40nm process (compared to the 55nm process of the G110M) the maximum power consumption stays the same. The later announced GeForce 310M for Arrandale laptops is just a renamed GeForce G210M.
The core of the G210M is internally called GT218 and according to Nvidia based on the current high-end desktop architecture (GTX 200 series). Furthermore, Nvidia has improved the micro-architecture for further power saving and performance increases. Therefore, the performance per shader unit should be slightly improved compared to the previous generation.
As the G 110M / 8400M GT, the G 210M 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 GeForce G210M also supports CUDA, DirectX Compute and OpenCL to use the shaders for other tasks than rendering images (like encoding videos or mathematical tasks). For these special tasks, the GPU can be noticeably faster than current CPUs. PhysX is not supported by the G210M because of too less shaders (for rendering and PhysX).
The mobile graphics card has a built in video decoder called PureVideo HD with VP4. The Video Processor 4 (VP4) supports the full decoding of H.264, VC-1, and now also MPEG-4 ASP (e.g. DivX or XviD). MPEG-1 still wont be supported, but the decoding of this codec is quite trivial on a CPU.
In conjunction with a chipset from Nvidia with integrated graphics (e.g. 9400M), the G 210M supports Hybrid-SLI (HybridPower and GeForceBoost). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista (and possibly Windows 7). Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost uses the integrated graphics core of the Nvidia chipset (e.g. 105M) and the dedicated of the G 210M in SLI mode to achieve better frame rates.
The performance of the entry level G 210M is on a level with the older GeForce 9500M G. Therefore, older or less demanding games should run fluently with medium to high details. Demanding DirectX 10 games, like Crysis, are playable only in low detail settings and low resolutions. Some games like GTA4 or NFS Shift wont even run in the lowest settings fluently. See below for a list of games we tested with the G 210M and the framerate we achieved.
Depending on the the used type of graphics memory (GDDR2, GDDR3 or perhaps even DDR2/DDR3) the performance may differ noticeably.
The power consumption of the mobile graphics card is - like the 110M - 14 Watt (TDP). Furthermore, according to Nvidia, the new improved core does only need half of the power in Idle mode.
