Radeon HD 4670 1GB vs Radeon R7 240
Intro
The Radeon HD 4670 1GB makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM runs at a speed of 1100 MHz on this specific model. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon R7 240, which uses a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this card. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to get to the maximum fill rate.
