Radeon HD 6670 vs GeForce GT 630 |
Released April, 2011
AMD Radeon HD 6670
- 800 MHz
- 1 GB GDDR5
by techPowerUp! (Apr, 2011)Perhaps targeting that segment while maintaining some feature-set cushion with "100% DirectX 11 compliance," AMD is releasing its new Radeon HD 6670 graphics card.

Released June, 2012
EVGA GeForce GT 630
- 810 MHz
- 1 GB GDDR5
by Doug-Crowthers (Apr, 2012)It is based on the Fermi GF116, which features 144 CUDA cores, 1.5 GB or 3 GB GDDR3 192-bit memory interface, 720 MHz core clock speed, and 891 MHz memory clock speed.

Features Key features of the Radeon HD 6670 vs GeForce GT 630
memory bandwidth Rate at which data can be read from or stored in onboard memory
Radeon HD 6670 | by techPowerUp! (Apr, 2011)Both overclocks are nice, especially the GDDR5 memory with its high-clock potential can help a lot.
pixel rate Number of pixels a graphics card can render to the screen every second
Radeon HD 6670 | by techPowerUp! (Apr, 2011)In this performance segment DirectX 11 support really doesn't offer much of a benefit, instead of improving performance by using the new API, all developers use it to add eye candy which reduces performance even more.
texture rate Speed at which a graphics card can perform texture mapping
Radeon HD 6670 | by techPowerUp! (Apr, 2011)For just $10 more you can get a HD 5750 and $20 more gets you a HD 5770, both of which offer more performance.
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
