GeForce GT 340 1GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be a lot superior to the GeForce GT 340 1GB in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M365X is a lot (about 110%) faster with regards to AF than the GeForce GT 340 1GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 19400 (110%)

Pixel Rate

The Radeon R9 M365X will be a lot (more or less 236%) better at full screen anti-aliasing than the GeForce GT 340 1GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 10400 (236%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
