GeForce GTX 650 vs Radeon R9 270X
Intro
The GeForce GTX 650 makes use of a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this card. It features 384 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare all that to the Radeon R9 270X, which has GPU core speed of 1000 MHz, and 2048 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.

2 Responses to “GeForce GTX 650 vs Radeon R9 270X”OK so why does my gtx 650 by glalxy in a 4 core w/4gb ram completely smoke my phenom II 6 core w/8gb ram r9 270x gaming series machine? And I do mean completely smoke... Anyone can answer this?
Josh, it all depends on what kind of game you're looking at. Knowing the specs of the 2 CPU's would actually help. If the 4-core rig's CPU is clocked higher, then that would win depending on what game you are testing out. If you're testing out MMO games or things that require CPU loadwork, a 4-core with higher clocks is better than a 6-core with lower clocks. Reason being, most games only use 2-cores max.
