3870 vs 4850

post #1 of 12
Thread Starter 
I would assume that the 4850 is much better than the 3870, but by how much?

are the 800 streaming processor units, much better than the 125-150mhz clock and memory differences?

Since the 4850 is clocked slower than the 3870.

to put it simply:
4850 = 9800GTX
3870 = 9600GT

its kinda big of a performance gap.

4870X2 = Swift kick to the nuts.
post #4 of 12
its 30%-50% faster than the 3870 depending on what game with AA and AF on the 4850 kills the 3870

In regards to 3dmark06 performance there is only about a 1000 point difference. In game performance is very different and the 4850 wins hands down by a very large margin.

I put my 3870 from this system into a little HTPC I put together - gotta love the HDMI output! I was a little disapointed that I could not get the crossfire to work with the 3870+4850. Not sure if anyone else has been able to do it.

Thank you for having this discussion. I"ve been debating on should I get two 3870's (since there so cheap after rebates) or one 4850. On paper the 3870 looks like it's slightly slower than the 4850 (until you look at the pixel fill rate). But since the 4850 arse rapes the 3870, I'll choose the 4850.

I'm going to purchase a projector and hook my rig up to it. The screen will be 100". The 2nd problem I'm having (besides deciding which card to get) is finding some site that's done a review of gaming on a projector. I've seen it only once in my life and fell in love with the concept.

Oh well...

Thanks again

I would replace the Cpu first , it will bottleneck the GPU( not by much since it's clocked @ 2.6 ,but still you'll be holding the Gpu back)... But if you really wanna get a projector , you should get one with at least 720p (should be quite expensive ). Also i'm not sure about the refresh rate, but i think they can handle games.
Just my 2 cents

The video cards are for my next build. I'm not going to do anything else with my current setup. I flirted with the idea of getting a:
ASUS L1N64-SLI WS (or whatever dual socket mobo I can find)
+
Dual Opteron 2350's
+
9800 GT
+
Cooler Master HAF932 Case

I know it's an expensive system that I won't tell my wife about.

Using this program to force my games (or whatever else I want) to use all 8 cores (I'm currently using it to force some games and programs to use both my cores)
Since most programs and games don't use more than 2 cores anyway, this program will be my justification for going 8 cores.

I don't mind having Eight cores @ 2.4GHZ processors rather than Two cores @ 3.4 GHZ or Four cores @ 3 GHZ processors. Either way it goes I know that I don't need to buy ANYTHING for my pc for the next 5 years (if a dual socket motherboard will last that long).

I kindly invite you to check the thread in my signature, where the HD3870 and HD4850 face off in nine different benchmarks, each stock, voltmodded, and overclocked.

But a 3870X2 would out perform a single 4850 right?
