Here is another source for the HD6xxx series

crossfiring that even if its possible is just a waste of money due to the performance being 2 Hd5870.

Hye guys, I'm planning on getting a TRad2 for my HD5870 (reference). I'll fix it together with my VRM-R4 cooler.

IN Thermalright website, they put up a compatibility table and for HD5870 with T-rad2 +vrm-r4 the compatibility is "conditional". What do they mean by that?

Guys, I have a question.

Currently I'm using 5770 Vapor-x on my Dell 20" (1600 x 900 reso), while I was playing Dirt2 on ultra (4xAA, Crowd & Shadows at low) It shows that I have 59frames performance... but in one of the race my monitor showed vertical rainbow stripes, music still playing and my PC reboots

I was using 10.7 official on that and I have reverted to 10.4, haven't test again though. Yes the card is OC'ed using the CCC autotune at 950 mem 1450 clk speed.

No problems with other games like MW2, SC2 and DragonAge all on Full settings with 8xAA.

Is it just the driver? or do I need to note on other things as well?

Ok I'll run Furmark for stability test? and I'll tune down the OC a bit.
Heat... It was running at 47 degrees on idle when I have 10.7 but was at 41 degrees on idle using 10.4, does it impact the performance?

My card is from Sapphire... MSI afterburner to run Stable test is ok? any other software I could run for stable testing?

Try out artic cooler S1 rev. 2 or twin turbo
1 of the best cooler for 4870

Quote from an old post of mine.
Nvidia would love to throw in a 2048-bit GPU this year, as it would certainly blow ATI out of the water. Except for the little fact that it'll cost them [insert huge number]% more to R&D and who knows how many more problems having such a wide bus would incur.

Keep in mind that the bit isn't some imaginary number. Somebody needs to draw them and use them!

AMD Barts specs leaked

256-bit bus, 960 shaders
Chinese tech site Chiphell has leaked an interesting slide featuring full AMD Barts specs and the numbers look impressive.

The new Barts series should succeed Juniper-based HD 5770 and HD 5750 boards, but it will deliver a significant performance boost. The biggest difference is the transition to a 256-bit memory bus, which will provide quite a bit more bandwidth than the 128-bit Juniper series. Both boards should feature 1GB of memory, but we’re still not sure about memory clocks, as we’re getting some mixed information.

Barts XT will feature 12 SIMDs, 960 shaders, 48 texture units and 32 ROPs. For comparison, Juniper XT packs 800 shaders and 40 texture units, so Barts will have 20 percent more of everything. The core should end up clocked at 850MHz and the TDP is rated at over 150W, which is quite a bit more than the HD 5770.

Barts PRO packs 800 shaders, 40 texture units and 32 ROPs, much like the current Juniper XT, but it will also have a wider 256-bus. It will be clocked between 700MHz and 725MHz and its TDP should end up below 150W.

AMD is pitting both boards against Nvidia’s GTX 460: Barts PRO will take on the 768MB version of Nvidia’s GTX 460, while Barts XT should fight the 1GB version. Judging by the spec, Barts boards should be able to outperform the GTX 460 and we wouldn't be surprised if they match HD 5830 or even 5850 performance in some scenarios, thanks to higher clocks and the 256-bit bus.

I'm curious to see what major performance boosts they managed with the card. The 800 shader 5770 and 1120 shader 5830 is well and truly beaten out by the GTX 460 right now.

The 6 series isn't going to double performance unless they nearly double everything.

When is Nvidia's 28nm chips coming out? If it is sometime in the next six months, AMD will be in trouble. Unless the 6 series isn't a full fledge series and more of a stopgap one and they intend to bring out the 7 series also within the next six months instead of Q4 2011.

8 true cores or included HT??

if all the games developers really optimized the code, we all can save some money. but look like they don't.

LOL! I love the word "FOOL".   

Actually, Core i7(Normal) should have only 4 Cores with the help of HT, it becomes 8 Threads(not 8 Cores).
However, Windows will recognize it as 8 Cores. 

In real world, most softwares/games do not use HT or more than 4 Cores(normally 2 Cores only). So, if you're into gaming, Core i5 750/760 is more than enough.
Softwares which like HT or more than 4 Cores are namely workstation software. For example: Autodesk 3DsMax, Blender, Autodesk Maya, Cinema 4D and so on.

I didn't say you're not right either?
Why are you firing at me? LOL.

hmm. the last time i was using Galaxy Nvidia 6600, temperature is from the nvidia driver itself. it should be correct right? since it knows what GPU im using

or what program you guys use to test your GPU temperature?

AMD's 6870 coming in November

Early silicon doing very well

IT LOOKS LIKE ATI's, sorry AMD's, 6870 is on track and doing quite well. Early word from AMD central has two big thumbs up.

We have already told you about the first member of the ATI's, sorry AMD's, Northern Islands family taping out, it is called Barts. Barts is a mid-range part aimed squarely at the Nvidia GF104/GTX460 chip, likely called the HD6770. It is due out really soon and should obliterate the competition.

Cayman, the big brother to Barts, taped out a little over a month after Barts, so it was expected to hit the streets a little after a month from Barts as well. This would put the 6870 on the streets in mid to late November. SemiAccurate's sources tell us that that is exactly what is happening.

Shipments to OEMs are going to start around the same time Barts/6770 hits the street. This puts cards 2-4 weeks out, well in time for Black Friday. Unlike previous Black Friday rumors, this card is real, not a puppy wielding wood screws.

In another turn of events, unlike the last round of cards bearing the last three digits of 870, this round should have very plentiful supply. While there will always be initial shortfalls due to demand, this time around wafer supplies are much higher. To top it off, yields are very good, the first batch of silicon from the fab is yielding far better than 5870/Cypress did at the same stage.

The end result is November should have a plentiful supply of Northern Islands cards, both 67x0 and 68x0s. If demand isn't insane, dual Cayman cards, aka Antilles, should be on the market as 69x0s before the end of 2010. If demand is too high for the 6870, then 6970 may be delayed a bit until there is adequate supply. ATI, sorry AMD, did learn from the last time.

Stick around, the rest of 2010 is going to be very exciting from a GPU standpoint, and early 2011 looks just as good. Unless you are an Nvidia stockholder, then it won't be nearly as fun.S|A
