The Nvidia Geforce GT 220 is not a rebadged card whatsoever. It's based on the same architechture that powers the GT200 GPUs. It has double the amount of register file space over the Geforce 8/9 GPUs and the brand new VP4 decoder unit that can decode MPEG4 ASP.
Here's a few things you can do on the GT 220 that you can't do on previous generation GPUs.Device 0: "GeForce GT 220"
CUDA Driver Version: 2.30
CUDA Runtime Version: 2.30
CUDA Capability Major revision number: 1
CUDA Capability Minor revision number: 2
Total amount of global memory: 1073414144 bytes

Compute mode: Default (multiple host threads can use this device simultaneously)
Nvidia has also improved the H.264 decoding performance, now VP4 can do 64FPS, the older generation hardware with VP2(mostly Geforce 8/9 GPUs) can only do 45FPS and VP3(8200/8300 chipset, 9300/9400/Ion chipset, G98 GPU) can only do about 51FPS.Specifications for Compute Capability 1.2
Support for atomic functions operating in shared memory and atomic functions operating on 64-bit words in global memory (see Section B.10);
Support for warp vote functions (see Section B.11);
The number of registers per multiprocessor is 16384;
The maximum number of active warps per multiprocessor is 32;
The maximum number of active threads per multiprocessor is 1024.
The reason this particular card has lower performance is because it only has DDR2 memory instead of GDDR3, it only has half the bandwidth so it's crippled. The GDDR3 versions of the GT 220 has much higher performance over the DDR2 cards. See the benchmarks on Tomshardware, it comes very close to the 4670 in performance.NVIDIA(0): NVIDIA GPU GeForce 210 (GT218) at PCI:4:0:0 (GPU-0)

This review is also somewhat disappointing because it doesn't even use the latest Nvidia 190.42 drivers.

The people in this forum seems pretty clueless, if you don't know anything, don't even bother to post and spread misinformation.
