Radeon HD 5850 vs Radeon HD 7850
IntroThe Radeon HD 5850 uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 1440(288x5) SPUs along with 72 Texture Address Units and 32 Rasterization Operator Units.Compare those specifications to the Radeon HD 7850, which uses a 28 nm design. AMD has clocked the core speed at 860 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7850 should perform a bit faster than the Radeon HD 5850 overall. (explain)
Texel RateThe Radeon HD 7850 is a bit (more or less 5%) faster with regards to texture filtering than the Radeon HD 5850. (explain)
Pixel RateThe Radeon HD 7850 is just a bit (about 19%) faster with regards to full screen anti-aliasing than the Radeon HD 5850, and also able to handle higher screen resolutions without slowing down too much. (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 MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to 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 😉
