GTX 670 SLI Results

[Don Karnage]

Amd's screwed.... Now i wish i waited on my 7850

670 SLI

670 SLI Overclocked

 

[Silverforce11]

I knew it. Look at the core clock on non-OC default, with the gigabyte windforce and custom PCB, getting above 1.2ghz turbo out of the box. Obviously putting it close to reference gtx680 which typically turbo to 1.1ghz or so non-OC.

OC, its hitting 1.34ghz, better than reference 680s, which need fancy cooling to achieve 1.3ghz.

I doubt reference short PCB 670 can turbo this high, obviously its more in-line with its pricing as it should fall around 10-15% slower than gtx680. BUT, custom 670 = best high end card.

Edit: It's obsoleting the entire gtx680, 79xx and the 7870 series at the current pricing scheme. 7850 is still fine at $249 (some are ~@220 now), different pricing tier, mid-range.

These results pretty much sold me on ditching amd for nvidia

I think after my failed experiment with 4870X2 and Gtx 470 SLI I am going multigpu again

4870X2 drivers were horrible but what was wrong with 470 SLI?

If you want to pay $419 for it, sure.

It's essentially a gtx580 + 30% (assuming gtx680 is +35% from a variety of games) out of the box. A bit more with OC. While awesome, it's in a different pricing tier than $220 - $249 cards. Your 7850 @ 1.3ghz is a gtx580 +10-15%.

that's what happend when un-controlled turbo, and cherry picked cards...

retail cards will be diferent...

We'll see. If amd drops prices on everything i may stay amd.

I dunno bout cherry pick, but these are not reference, they are factory OC models on good pcbs and cooling. From pricing leaks, its $419 for one of these. The reference short 670 is ~$399.

Heat.I am not comfortable with water cooling.

 

[aaksheytalwar]

If these are $419 then reference should be 379, there won't be a single taker at 400

 

[Silverforce11]

Also note, these factory OC custom 670 already hit 1.15 - 1.2ghz turbo on default. When OC to the max, they reach 1.34 and a bit below that as shown above (so average 1.3ghz). That's a very small headroom on top clocks. ~10% OC potential only.

In terms of performance gain on 3dmark, its only a ~5% point gain for a 10% OC. <-- Scaling not so hot, bandwidth limited?

Why not? Its so easy

This is what people are missing

It's not the next coming.. but its still very good and would have to force a price drop on the current line-up if supply is good. There's no way the 7870 should be $349 when these are around.

Amd has to drop prices. The 7950 needs to be 350 as it'll be destroyed by the 399.99 670

A reference 670 will be 10% slower than a custom 670 at stock making it within 5-7% of a 7950 and the 7950 has more oc potential. Though a $375 price would make it more than competitive if it is for a custom 7950 when reference 670 costs $400

Why should AMD drop their price against these Nvidia Vaporware?

7850 is AMD's saving grace in capturing the mid-range market share.

Why not? Its so easy

The dealer made me feel uncomfortable with all the leakage talks
I mean is leakage really common?

I've only had one leak and it was because of my own dumbassness. 99.9% of the time you're golden

 

[Jacky60]

Probably because an air leak or spill onto your mobo/cards won't fry the fricking lot unlike water! You had a leak resulting in what? From what you say you've assembled water cooling around 1000 times to make the 99.9% stat valid!

The only people who have leaks are the ones who don't take there time and are careless

Thx for sharing this :thumbsup:
I may go for water cooling for gtx 670 sli.
