Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 7850
IntroThe Radeon HD 5850 features a GPU core speed of 725 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1000 MHz through a 256-bit bus. It also is made up of 1440(288x5) Stream Processors, 72 TAUs, and 32 ROPs.Compare that to the Radeon HD 7850, which has core clock speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7850 should be 20% quicker than the Radeon HD 5850 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 7850 will be just a bit (approximately 5%) more effective at AF than the Radeon HD 5850. (explain)
Pixel RateThe Radeon HD 7850 should be a bit (about 19%) better at full screen anti-aliasing than the Radeon HD 5850, and able to handle higher resolutions while still performing well. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 video 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 number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the 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 😉
