Radeon HD 5850 vs Radeon HD 7850
Intro
The Radeon HD 5850 uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.Compare those specifications to the Radeon HD 7850, which uses a 28 nm design. AMD has set the core speed at 860 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 the 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 the card's clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum 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 😉
