Geforce GTX 670 vs Radeon HD 4890 1GB
Intro
The Geforce GTX 670 has a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.Compare all that to the Radeon HD 4890 1GB, which features GPU core speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 975 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

Comments
One Response to “Geforce GTX 670 vs Radeon HD 4890 1GB”I have both cards on my Desktop
I buyed in 12/2012
Cpu: Intel Core i5 3570K
MoBo: Asus P8z77-vlk
And GPU: Club Ati Radeon 4890 1 GB
3D mark Vantage give GpuScore 11 901, with game booster
I buyed last month Gigabyte GeForce GTX 670 x3(Cooler is x3, not 3xsli)
3D Mark Vantage give about 32 207 without tweaks like Gamebooster.
