AMD Radeon HD 6850 Overclocking Roundup: Asus, XFX, & MSI
by Ryan Smith on November 8, 2010 12:40 AM ESTThe Test & Stock Gaming Performance
For our testing we’re using the 6800 series launch drivers: AMD Catalyst 10.10.
| CPU: | Intel Core i7-920 @ 3.33GHz |
| Motherboard: | Asus Rampage II Extreme |
| Chipset Drivers: | Intel 9.1.1.1015 (Intel) |
| Hard Disk: | OCZ Summit (120GB) |
| Memory: | Patriot Viper DDR3-1333 3 x 2GB (7-7-7-20) |
| Video Cards: |
AMD Radeon HD 6870 AMD Radeon HD 6850 AMD Radeon HD 5870 AMD Radeon HD 5850 AMD Radeon HD 5770 AMD Radeon HD 4870 NVIDIA GeForce GTX 480 NVIDIA GeForce GTX 470 NVIDIA GeForce GTX 460 1GB NVIDIA GeForce GTX 460 768MB NVIDIA GeForce GTX 285 NVIDIA GeForce GTX 260 Core 216 XFX Radeon HD 6850 MSI R6850 OC Asus EAH6850 |
| Video Drivers: |
NVIDIA ForceWare 260.89 AMD Catalyst 10.10 |
| OS: | Windows 7 Ultimate 64-bit |
As we do have a couple of overclocked cards in today’s roundup we’ve gone ahead and quickly run a subset of our benchmarks. There won’t be any surprises here, as the MSI card is the only card with a significant overclock, pushing it ahead of the reference card, the XFX, and the Asus 6850s but not being enough to significantly chance the performance of the card.
The Asus with its sub-2% overclock doesn’t make any notable headway here. Meanwhile the MSI R6850 OC with its higher overclock does manage to top the Radeon HD 5850 at times, depending on how big the gap was in the first place. Whereas the stock 6850 is undeniably slower than the stock 5850, we’d be comfortable calling the R6850 OC comparable to the 5850.

However the card is nowhere in the graphs. Yet 5770 is there .... I was actualy interested in that comparison. thanks for the good work.

I actually don't have the GTS 450 on the new test suite. We'll be updating Bench this next week, at which point it'll show up.Marburg U - Monday, November 8, 2010 - link

I would actually love to see the GTX 460 FTW in these charts because 850 mhz is a typical OC you can get from any regular GTX 460. The 460 and the 6850 are direct competitors so having both their overclock results side by side would be nice.kmmatney - Monday, November 8, 2010 - link
I have a HD4890, which is a power hog, yet I can run it at near silence, fully overclocked, with an Accelero S1 Rev 2 and a whisper fan. Too bad they don't offer a card with this sort of cooler pre-installed - then it would be possible to overclock these cards and still keep a quiet system. I wonder if this cooler will fit on these new cards? The cooler worked great onteh HD4890, but I did have to buy an extra heatsink for the VRMs (and had to hacksaw that to make it fit).Pantsu - Monday, November 8, 2010 - link
Can't the XFX cooler be adjusted with a tool like Afterburner? I mean that would solve the noise issue afaik. But if it's stuck that way there's no reason to buy it.casteve - Monday, November 8, 2010 - link
+1. Why not use Afterburner to remove some of the variables and see how the tested coolers stack up db vs temp?Oxford Guy - Sunday, November 14, 2010 - link

Newegg's Lowest prices (11/8/2010):HD 5870 1GB.................$299.99 (plus $2.99 shipping)
GTX 470 1.28GB............$249.99 (free shipping)
HD 6870 1GB.................$239.99 (plus $7.56 shipping)
HD 5850 1GB.................$239.99 (free shipping)
GTX 460 1GB..................$189.99 (plus $3.99 shipping)
HD 6850 1GB.................$179.99 (plus $7.56 shipping)
GTX 460 768MB.............$159.99 (free shipping)
GTS 450 1GB .................$109.99 (free shipping)
Just comparing the above, there's really two competitive ranges:
The $239.99 to $249.99 price range which includes the GTX 470 1.28GB, the HD 6870 1GB, and the HD 5850 1GB.
The $179.99 - $189.99 price range which includes the GTX 460 1GB, and the HD 6850 1GB.
How, if we're going by OVERCLOCKED comparisons for a SINGLE card, especially at the highest two resolutions (1920 x 1200 and 2560 x 1600):
1. The GTX 470 1.28GB overclocked definitely edges out both the overclocked HD 6870 1GB and HD 5850 in performance, while the HD 6870 1GB would be my pick over the HD 5850 1GB, both being the same price.
2. The GTX 460 1GB and the HD 6850 1GB are both great cards. However, seeing the Max Overclock for the HD 6850 with a Max Overclocked Voltage at 1.22v being 960MHz, and a Max Overclock witnessed for the GTX 460 1GB with a Max Overclocked Voltage at 1.087v being 1015MHz (most are in the 880MHz - 950MHz range), the GTX 460 1GB has a greater potential of overclocking ability than the HD 6850. Given that a GTX 460 1GB overclocked slightly betters that of a GTX 470 1.28GB at stock, the winner is obviously the GTX 460 1GB.
Please include the GTX 460 1GB overclocks when comparing overclocks with the HD 6850. Most of us are mature and smart enough to make our own decisions based upon test results, rather than guesswork. Those that are biased one way or another are going to believe what they want no matter what. All that we really losing out on, is our confidence that the site that's doing the review is behaving the same way. If we don't see it here, we're just going to go see it somewhere else.
