NVidia launch entry level GeForce GT600 cards

Earlier this week, NVidia launched three new 600-series entry level GPUs, GeForce GT610, GT620 and GT630. GT610 has 48 CUDA cores, and the same specs as GT510 (OEM). GT620 and GT630 each have 96 cores, and appear to have the same core as GT530 (OEM), so all three GPUs are recycled from previous products.

GT610 has 48 cores running at 810 MHz. With 8 texture units, the texture fill rate is 6.48 gigatexels/s. It has 1024 MB DDR3 memory, with an effective clock speed of 1.8 GHz on a 64-bit bus (giving 14.4 GB/s bandwidth). These specs match the upper end of the GT510 (OEM) reference specs.

As the table above shows, GT620 has the same specs as a GT530 (OEM), with 96 cores clocked at 700 MHz. The 16 texture units provide a fill rate of 11.2 gigatexels/s. It also has 1 GB 64-bit DDR3 clocked at 900 MHz, providing a bandwidth of 14.4 GB/s.

GT630 comes in two flavors, supporting GDDR5 or DDR3 memory. It has 96 cores clocked at 810 MHz, with 16 texture units providing a throughput of 12.96 gigatexels/s. The GDDR5 version has 1024 MB memory clocked at 800 MHz (3.2 GHz effective) on a 128-bit bus, providing a bandwidth of 51.2 GB/s. The DDR3 version has a memory clock of 900 MHz (1.8 GHz) on a 128-bit bus, providing a bandwidth of 28.8 GB/s.

All the new models are available for immediate purchase.
