AMD Radeon HD 6000-series GPU Shots Leaked

by - source: Tom's Hardware US

The first peek at the next-generation AMD graphics offerings.

AMD will be back on the GPU offensive this fall with new offerings. According to DigiTimes, Radeon HD 6000-series will launch first with the HD 6700, which will replace the market currently occupied by the Radeon HD 5770 and 5750.

While AMD's exact launch plans are still unknown, today we get to see some supposed leaks thanks to Chinese source Chiphell. Posted on the forums are pictures of Cayman and Caicos engineering samples, which are believed to be the "Cayman XT" Radeon HD 6870.

The other card is presumably Caicos, which could be part of the Radeon HD 6300 series for entry-level or HTPC. This example has 1GB DDR3 64-bit memory, with a core clocked at 650 MHz and memory at 800 MHz.

This is what the chip looks like, and it supposedly scores P17xx in 3D Mark Vantage, which compares to the P12xx to P13xx range on the HD 5450.

Yum yum yum, but the 6000 series are a mid-gen mash-up, aren't they, not the actual next-gen tech.

Well, my life has just become more complex - just after settling on some Gigabyte SOC GTX 470 SLI goodness after a long period almost going 5870 TOXIC Crossfire, the 6000 series may well be available for when I put this monster build together. Damn you lol

Ponder ponder ponder - do I game or video edit more?

Munch, I feel like my Radeon Mobile 5850 will be ruined much sooner than I expected.
(rant) Anyway AMD is, I feel, where nVIDIA were 4 years or so ago. On top of the winning innovations tsunami.
Good job !

A mobile GPU get's outdate pretty fast indeed, but I guess it will be a decent gaming GPU for a while.

The ATI 6000 is hardly a winning innovation. Instead, it's a refresh that acts as a stopgap until 28nm manufacturing processes mature (which takes longer than expected). The 6000 series won't leave your 5000 series outdated, so don't worry.

ATI is indeed doing very well, but don't exagerate. They're king in both value for money and performance per watt in the discrete desktop segment and still have the most powerful discrete GPU on the market, but that's but a part of the picture. In the mobile market, Nvidia is more or less on par with ATI. AMD lacks a strong HPC line-up for scientific computing similar to Nvidia's Tesla series. The Quadro workstation line is more than a match for the FirePro series, although most of that is due to a driver advantage that ATI could still fix. AMD has no reply to Tegra 2, which might see some succes with the rapid growth of tablet and high performance smartphone market.

ATI is doing really well, but Nvidia isn't dead either.

But if this is the same-gen tech as 5xxx series, how will they actually be superior to them? For example, if the 6850 is manufactured on the same die process as the 5850 won't it just be the same, with neither improvements in power consumption nor performance?

It's a refresh. Imperfections in the old design are corrected, energy efficiency is improved here and there, due to better yields they can up the clocks a bit,...

So for short, they hone an existing design to perfection by squeezing every little bit out of it and then add some new features.

Compare it to the Phenom II X6's. The fundamental architecture remained the same, but power gating, extra cores and minor improvements meant that they could add 2 more cores without changing TDP and things like that.

So a 6850 will consume slightly less power and perform slightly better than a 5850.

Ah ok, thanks for clearing that up for me Silmarunya. Funny you should choose that example though of the Phenoms, because I was waiting for the X6 before upgrading, only to find poorer overall performance than I expected, causing to go for an X4 965 instead! :)

Darn, Just when i was able to afford a HD5970...
Question: since the 6k series are made on a similar die process,would u be able to crossfire them with 5k series cards? Eg a 5850+6850??

ATi might be on a wave crest but their Crossfire performance is really poor compared to SLi from nVidia. Buying 2 x 5870 cards was also going to be my plan but when I saw the numbers, a single 5970 was far more attractive. I mean some games only get a 10 - 20% boost in crossfire mode and when that is all you are getting with a whole extra #500 card in your system (and all the power consumption and heat that goes with it) then that is poor.

I stick to the last and best of ATi, the 5970..and probably get a second when i upgrade to a bulldozer...im not realy impressed by the 6k series especialy considering the fact that the 6870 probably wont be as fast as two 1gb gtx460s..

fake! why? cause there is ATI logo on the first picture, but AMD dropped the ATI brand.. so 6 series will have AMD logo not ATI!!!!!!!!!!!!!!!!!!!!

Not wanting to get into a fanboy rant, but Nvidia has the current fastest single GPU, the GTX 480. The ATI 5970 is x2 5870 GPUs (underclocked to 5850 speeds) and with all the performance shortcomings of ATI crossfire compared to Nvidia SLI.

I'm not even sure ATI have the performance per watt title anymore, as GTX 460 SLI has snatched that, or if it hasn't, it's very close.

I think ATI is possibly the right way to go for a single card, mid price, mid power solution, but for anything high end or multi GPU, Nvidia has the lead.
