hello there i asked a couple questions sorta about this issue. i was thinkin about getting the 5670. then someone said no get the hd 4850. so i looked into it and i just dont get it. how is the 4850 faster in benchmarks and what not and charts, when the 5670 has a faster clock speed 775 to 625 faster effective memory clock 1000 to 960 and its ddr5 to ddr3 memory, but the 4850 has more stream processors 800 to 400 and its a 256 bit interface to 128bit for the 5670. ok this is my point are people saying the 4850 because its basically better at higher resolutions and with stuff turned up it just way out performs the 5670? please help me i'm not an overclocker so that doesnt matter i was always afraid i would fry somethin so i dont mess with it.
based on raw performance the HD4850 is better than 5670 (even 4770 is better than 5670) . the 5670 is more close to 9800GT in term of performance but still, in dx9/dx10 games 9800GT still take the lead over 5670. you can see this on bechmarks
The 4850 beats the dog piss out of the 5670 in performance. The only thing the 5670 has going for it over the 4850 is that it has DX11 ... but the 5670 isn't really fast enough to play DX11 games well anyway, so there's really no point.
Basically, the only use for the 5670 is if you have an early-model dual core system with a small power supply, small monitor, and limited budget, and you want to meet the minimum technical requirements to play DX11-only games, which probably won't be out for a year yet. So there's essentially no use for it now, and certainly not at that price.
is the bit thing important. as in the 4850 is 256 bit and the 5770 is 128bit. wouldnt that make the 4850 better cause it can send more data twice as fast
the 5770 and 4850 have different builds, the 4850 does have a 256 bit interface but the 5770 has faster RAM and a better GPU. Comparing cards based on spec is like comparing food based on a picture. Just like you need to taste the food to make a decision, cards need to played with games to see their performance.
Most card reviews will display competitive cards and their performance also, that would be your best bet to see what cards are faster. Comparing specs will just confuse you and waste your time.
