NVIDIA pulled out their rebranding stamp today and stamped two new GPUs to put on the OEM-only table. The two "new" GPUs in question were the GeForce GT 520 which are now known as the GeForce GT 620. Yeah.
This new part is identical to its predecessor, except that the memory has been halved from 2GB to 1GB, or 1GB to 512MB. But, sit down because this is going to blow you away, NVIDIA added that the GT 620 now supports the OpenGL 4.2 API, something its predecessor doesn't have. Wowee.
The GT 620 is still based on the 40nm GF119 silicon, sporting 48 CUDA cores, 8 TMUs, and 4 ROPs. The other GPU is the "new" GeForce 605, which is a re-branded GeForce 510. Again, based on the GF119 silicon, the GeForce 605 core runs at 523MHz, with 1046MHz CUDA cores. This model comes in memory sizes of either 512MB or 1GB.
