The GIGABYTE GT220 is based upon NVIDIA’s GT218 chip which has 480 million transistors on TSMC’s 40nm fabrication process. The number of Stream Processors on the GT220 card is 48 which compares to the 240 found on the GeForce GTX280 and the 512 SPs found on the Fermi card. In terms of TMUs, ROPS, the GT220 has 8 ROPs (Outputted Pixels), and 16 Texture Mapping Units.

The clock speed on the GT220 is overclocked from the reference GT220 at 720MHz. The reference GT220 runs at 625MHz, meaning that GIGABYTE has given the card a nearly 100MHz bump in core clock speed. The Shader clock has been set to 1566MHz, a 206MHz increase over the reference card. The memory speed on the card is 800MHz (1600MHz effective).

The GIGABYTE GT210 on the other hand is based upon NVIDIA’s GT218 chip which has 260 million transistors on TSMC’s 40nm fabrication process. The number of Stream Processors on the GT210 is 16 which is similar to that of the GeForce 9400GT which it replaces in NVIDIA’s lineup. The card has 64-bit memory clocked at 400MHz (800MHz effective) The number of ROPs is 4.

The memory bandwidth on the GT220 is 25.6GB/second which is the 1600MHz multiplied by 128-bits divided by 8bits/byte. This is adequate for a video card in the very budget category like the GT220 and GT210 but is dwarfed by the memory bandwidth of the other GeForce cards. On the other hand these cards are not retailing for $79 maximum. The GT210 has a memory bandwidth of 6.4GB/second with 512MB of GDDR3 memory.

The GT220 and GT210 are the first NVIDIA cards to support DirectX 10.1 which is a minor update to DirectX 10.0 mainly involving image quality improvements. It is the intermediate step between DirectX 10 and DirectX 11 however, and several games use DirectX 10.1 to improve performance on cards that support it by requiring less code to do the same thing. The GT220 and GT210 were originally released in OEM form where a checkmark on the feature list is more important. The GT220 supports PhysX in games that support it like Darkest of Days, Batman, Arkham Asylum, and Mirror’s Edge. Unfortunately, NVIDIA decided not to support PhysX on the GT210 but that is likely due to the low performance of the card in games and limited number of SPs and not due to the inability of the card to run PhysX in the drivers, as any card can do those effects, but it taxes a card to do them.
