Evergreen is the name of the new generation of DX11 cards from AMD formerly known as the R800 generation. Evergreen is a family of trees in both summer and winter stay green. "Always green. Each segment has a specific name given: Hemlock, Cypress, Cedar, Juniper and Redwood.

Some sites link called Hemlock at the slowest GPU. My sources say however that this is a mixup and that appropriate Hemlock is the fastest GPU will be linked to a HD59x0 card. If X2 is a solution or that this is a fast single GPU solution is not clear. Suffix X2 missing until now is because the roadmaps.

RV870 will probably be a lot faster than RV770 (70-100% depending on the situation and how a game is programmed (pure DX11 would com much faster, thanks to multithreading, compute shaders and Tesselations). The first samples arrive in Q2 09 out and the final card will be in the second half of 2009 are released. RV870 is a 40nm GPU as RV740.

The R8x0 generation has no UVD3 board as previously mention, but "Enhanced UVD2" that hardware decode acceleration of dual 1080p HD video streams lower runs. The changes are not drastic enough to completely new song to justify. The notebook GPUs come out under the heading of Manhattan and are based on the desktop variant.

R800 also has something that still listens to the mysterious name "Dual Shader Engine. This name seems to have completely expired. But it boasts the second generation TeraScale engine and will more than 2 Tflop managed to pump out at Cypress XT (HD5870). The term ATi Eyefinity will also be promoted as a new feature. The observant user has of course already leaked pictures on the web view. Contain a lot of connectors. From Catalyst 9.10 (8.66) will be possible to connect three monitors to your HD5870 (Cypress XT), where previously only two could be controlled. Whether this feature on the HD5850 (Cypress Pro) is still waiting. The possible combinations are DVI / DVI / DP or DVI / HDMI / DP and will be a converter included each signal to another signal conversion.

Furthermore it introduces Brighter Whites processing what the blue value of white color raises a bright and vivid video playback. Video and Independent Gamma Control ensures that your video gamma alone could arrange your desktop range for even better viewing experience.

Not only in reproducing it improves a few things. ATI we used that they come with something rejuvenates came in IQ. So they were the first to 6x MSAA, they released the first HiQ AF, Temporal AA and gamma corrected AA and they came with a usable form of Edge Detect AA. The Evergreen generation AMD will continue in this area and will have the texture quality to be pushed to a new height. And this is just one of many surprises that Evergreen generation will bring.

Who's more with a DX11 card? I dare much money to work on AMD. The latest roadmaps show Q3 (September). 10 September to be exact.

Update *:
HD5870 (Cypress XT): ~ P15xxx / P17xxx
HD5850 (Cypress Pro): ~ P1? Xxx
Juniper XT ~ P95xx
Redwood ~ P46xx

* Please note that this "rumor" until the final launch is. It's what I learned, but is no guarantee of final scores. For the same money I greatly fooled. And the final performance may vary depending on CPU and used driver version.

Chiphell have got their hands on pictures of AMD/ATI's much anticipated next-generation DX11 cards, codenamed "Evergreen", releasing September 10th.

ATI have done away with the numerical RV***/R*** nomenclature and are only calling them by codenames now. There will be four classes of the Evergreen range - performance "Cypress", performance-mainstream "Juniper", mainstream "Redwood" and entry-level "Cedar". The flagship will be the dual-chip Cypress, codenamed "Hemlock". On a side note, all these codenames are derived from coniferous trees, which are incidentally 'evergreen', or have leaves all year round. It is clear that ATI have great confidence in the upcoming generation.

The first set of pictures are reportedly of "Juniper" or RV840, the successor to the Radeon HD 4770, in the mainstream segment. Indeed, the cooler is very reminiscent of the original dual-slot stock cooler on the 4770, this time with black outfitting, on the PCB as well. At the rear end is a host of output ports, what looks like 2x DVI ports, an HDMI and a Displayport. It is worth noting that the exhaust vent only takes half the space on one slot - which might indicate an efficient and cool (thermally as well as aesthetically) card. Juniper does, however, come with a 6-pin power connector, which would indicate a TDP above 75W, if barely so (like the 4770).

In the performance segment, ATI are offering "Cypress" or RV870, which will succeed RV770/790 (HD 4800 series), rumoured to be branded as ATI Radeon HD 5850 and 5870. The heatsink and top view pictures are available. It is unclear if this is the high-end Cypress XT, and of course, these pictures should be taken with a grain of salt. Unlike the Juniper cooler, which is similar to a design introduced for the 3870 - the Cypress cooler seems novel. The Cypress card does seem to be longer than the reference 4850/70/90, which were in the 9" range. It would appear as long as the 4870 X2 or the GTX 200 cards, which are in the 10.5" range. The die size does not appear to be as large, definitely much smaller than nVidia's GT200 chips, and around the same size as RV770, at first glance. Which would beg the question, did ATI really need a full length cooler? If so, what kind of cooling would the rumoured dual-chip "Hemlock" require? It is quite possible ATI is playing it safe, as one of the major criticisms of the 4800 series was the high temperatures. It requires 2 x 6-pin connectors, which would suggest a TDP of between 150-200W, much like the 4870/90. The rumoured system requirements suggest a 500W PSU, or 600W if running in dual-card CrossfireX mode. So, the power requirements seem reasonable and within the range of the 4800 series.

According to rumours, these could possibly be the specifications:

Cypress - 1600SP, 256-bit, 80 TMU, 32 ROP
Juniper - 800SP, 128-bit, 40 TMU, 16 ROP

These specifications do seem realistic. However, ATI have a history of spreading false rumours about their cards. (Remember RV770? They convinced the entire world the card had 480SP, when in fact they had 800SP!) A significant step forward for ATI would be the 32 ROPs (render output units) on the RV870, if indeed these rumours are accurate. All ATI high-end GPUs have sported 16 ROPs since the X800 series way back in 2004.

RV830's specifications are a dead match for the RV770 4800-series, except for the 128-bit. Considering the 4850 was largely bottlenecked by the slow GDDR3, and significantly outperformed by its GDDR5 siblings (4870/90) even adjusted to similar clock speeds, ATI must surely be using unprecedentedly high frequency GDDR5 memory for both GPUs - possibly reaching 5 Gbps. This would put the memory bandwidth in the region of 150 GB/s for RV870. For a 1600SP monster, there might still be a bottleneck. There have been rumours of a 384-bit memory bus in the past as well. No clock speeds have been revealed thus far, and all leaked speculations should only be considered as rumours.

At this stage, the Evergreen generation looks promising, and ATI have a good headstart over nVidia's rumoured GT300 series, which are taped out and will only be arriving mid Q4-09 at the earliest.
