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 D-A (Aug, 2012)I can't say the 630 blew me away, I knew it would run some games, but this card is just a really amazing value right now for a low end system running old and new games.

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
GeForce GT 630 | by monzawa (Feb, 2013)The onboard ram is fast of course and the fan seems sturdy enough.
pixel rate Number of pixels a graphics card can render to the screen every second
GeForce GT 630 | by Bob--Bob-in-Big-Bear-CaWith the GT630 WoW automatic settings set the graphics to high and I get 30-36 fps and the game play is much smoother (no jumping or lag from the graphics side).
texture rate Speed at which a graphics card can perform texture mapping
GeForce GT 630 | by Peter (Dec, 2012)I am not a gamer and some have said this in not the best choice for video games; that said, this is the first budget card I have had that will run the nVidia Human Head Demo smoothly which among other things I use a benchmark.
floating point performance How fast the gpu can crunch numbers
GeForce GT 630 | by JV (Mar, 2013)I needed this to be able to speed up some very graphics-intensive games and it does just that.
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
