Default Hd 4670 vs hd 3870

I'm trying to decide between the two. The price is the same, give or take 10$. The 4670 is newer and has some perks but, the 3870 seems to be the strong card.

I was reading this review to get an idea. They said so many good things about teh 4670 that I was pretty confident it was a great buy. However, I looked at the specs on the 3870 and, well, the numbers are much higher.

ProductStream ProcessorsCore SpeedMemory SpeedMemory BusTransistors
HD4670320750MHz2GHz GDDR3128-bit514M
HD4870800750MHz3.6GHz GDDR5256-bit956M
HD3870320825MHz2.25GHz GDDR3256-bit667M


3870 looks pretty good no?

Here's the cards I'm considering off newegg.


Newegg.com - SAPPHIRE 100225DDR3L Radeon HD 3870 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards

vs

Newegg.com - HIS Hightech H467QS512P Radeon HD 4670 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards

(first post. Can't do links. Will edit shortly.)

Whatcha think?

If you have another suggestion for a $100 or less card I'm open.

Thanks fellas. Appreciate the input.

***side note***

I'm behind the times. Still running a AMD 939 socket cpu, PCD 3200 ram and other things you'd expect from a build like that. Oh, 400w Antec PSU.

I am very happy with my HIS IceQ3 Radeon HD 3870 card the only problem I had was that when I first bought the card there was a problem with the drivers in Linux OS but I cured that fast. on my Windows box it runs great I can Run any game it runs cool and compared to my old x800 card I had this thing is silent under loads

good to know. HIS has great cooling for sure. I've been NVIDIA ever sinve ATI 9600 xt Pro became obsolete lol.

So, do you see it the way I do? Seems like the only thing the 4670 is offering is a newer model,

I'm just a World of Warcraft gamer on a budget. Think the card will hang in there?

Of the 2 cards you linked, I'd probably go with the HD4670 since you seem to be on a tight budget so it's cheaper (before rebates). Also it has dual-slot cooling and doesn't require additional power.

The HD3870 needs additional power and your 400W PSU might be cutting it close. It's also only single-slot cooling so if you have poor case airflow it'll probably get hot and noisy.

Performance wise, the cards are pretty close to each other. Don't let the numbers in the specifications determine your choice. They are different GPUs so the way it uses it's resources is different.

Chances are you can overclock the HD4670 a fair bit since it has some decent cooling on it, though it's hard to say how far you can go with the HD3870.

You can get a 3870 for 64.99 after rebate at the NCIX weekly sale.

Great deal if you ask me!!

I just changed from 2x3870 to 2x4670. 2x3870 are more powerful and a bit perform better (maybe 10% if I were to guess) but the 4670s are much more power efficient. That is the trade off.

How did you find that relates to FPS in games that support Crossfire?

WIC 37 vs 45 FPS, Crysis 60 vs 62 FPS. Higher # is 3870.

That's not a bad trade off at all especially in Crysis. 60-62 would not really be noticeable. While playing World in Conflict could you see the difference between 37 vs 45 fps?
