GeForce GTS 150 vs Radeon R7 M265
Intro
The GeForce GTS 150 comes with a core clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon R7 M265, which has core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 24 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Memory Bandwidth
Both cards have the exact same bandwidth, so in theory they should perform the same. (explain)
Texel Rate
The GeForce GTS 150 should be a lot (about 172%) better at texture filtering than the Radeon R7 M265. (explain)| GeForce GTS 150 |
|
47360 Mtexels/sec |
| Radeon R7 M265 |
|
17400 Mtexels/sec |

Pixel Rate
If running with a high screen resolution is important to you, then the GeForce GTS 150 is a better choice, and very much so. (explain)| GeForce GTS 150 |
|
11840 Mpixels/sec |
| Radeon R7 M265 |

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
