Radeon HD 5850 vs Radeon HD 7850

Intro

The Radeon HD 5850 makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 1440(288x5) SPUs along with 72 TAUs and 32 ROPs.

Compare all of that to the Radeon HD 7850, which uses a 28 nm design. AMD has set the core speed at 860 MHz. The GDDR5 memory works at a speed of 1200 MHz on this model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per 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 clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

Hey Im looking at possibly upgrading my video card in couple of months.
I currently have radeon hd 5850 and was wondering whats the main difference when cards say core speed and memory speed?
I see cheaper cards on the market have the same core speed but are DDR2 instead of 3.

@Terrence .. core (clock) speed like any of the other measures of performance in gfx cards is all relative. You mention lesser cards having "the same core speed" .. and that's actually incorrect across each generation iteration of DDR & GDDR vRAM types. That's to say, a gfx card with 1GB of DDR2 vRAM will essentially perform no better than a card with 512MB's of GDDR3 vRAM. You see, the premise being that each generation of DDR roughly doubles the speed of the generation before. So, put another way, 1 GB of GDDR3 will perform at only half the speed of 1 GB of GDDR5. So, it's like this, DDR2 & DDR3?? Forget it .. they're yesterday's tech' - and a complete waste of time even thinking about (let alone discussing). If you're after a budget upgrade in the RED corner, i'd advise a HD6950 2GB - or better still a 6970, at the very least. If you're looking at the GREEN team, consider at least a GTX 480 or GTX 580. As all of those cards are getting relatively old now (but each still supporting DX 11 & all having GDDR5 vRAM), you should be able to pick up a bargain from either the GREEN or RED Team on any one of those cards i've named ;)
