Radeon HD 6450 (OEM) 1GB vs Radeon R7 240

Intro

The Radeon HD 6450 (OEM) 1GB uses a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory works at a frequency of 900 MHz on this particular model. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Compare those specifications to the Radeon R7 240, which has core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240 30 Watts
Radeon HD 6450 (OEM) 1GB 31 Watts
Difference: 1 Watts (3%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R7 240 should be much (approximately 143%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)

Radeon R7 240 14600 Mtexels/sec
Radeon HD 6450 (OEM) 1GB 6000 Mtexels/sec
Difference: 8600 (143%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 240 is a better choice, by a large margin. (explain)

Radeon R7 240 5840 Mpixels/sec
Radeon HD 6450 (OEM) 1GB 3000 Mpixels/sec
Difference: 2840 (95%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
