AMD Cypress ''Radeon HD 5870'' Stripped
Here are the first pictures of the obverse side of Cypress' PCB, and the first pictures of the centre of attraction: the AMD Cypress GPU. CzechGamer dissembled two Cypress "Radeon HD 5870" cards for a quick blurrycam photo-session. The PCB shot reveals quite a bit about Cypress, particularly about the GPU.
To begin with, the GPU is AMD's overhaul on transistor counts, and a bold work of engineering on the 40 nm manufacturing process, given the kind of problems foundry partners had initially. Apparently they seem to have recovered with most of them, as AMD's AIB partners are coming up with new products based on the 40 nm RV740 GPU on a weekly basis. The package holds a "diamond-shaped" die that is angled in a way similar to RV740, RV730, or more historically, the R600. The seemingly huge die measures 338 mm² (area), and for 40 nm, it translates to "huge", and is vindicated by the transistor count of ~2.1 billion. In contrast, AMD's older flagship GPU, the RV790 holds 959 million, and NVIDIA's GT200 holds 1.4 billion.The PCB has three distinct areas: the connectivity, processing, and VRM. To fuel the GPU is a high-grade 4 phase digital PWM power circuit, while the PCB has placeholders for an additional vGPU phase. The 8 (or 16 on the 2 GB model) memory chips, is powered by a 2 phase circuit. Power is drawn from two 6-pin PCI-Express power connectors, but there seems to be a placeholder for two more pins, i.e., to replace one of those 6-pin connectors with an 8-pin one. Bordering the GPU on two sides are the 8 GDDR5 memory chips, which AMD calls says is generation ahead of present GDDR5, and supports reference frequencies as high as 1300 MHz (2600 MHz DDR, 5.20 GHz effective). In the 2 GB variant, 8 more chips seat on the other side of the PCB. This is what perhaps, the backplate is intended to cool. On the connectivity portion of it, are the two CrossFire connectors, DisplayPort, HDMI and a cluster of two DVI-D connectors. There has been a raging debate about how adversely the small air vent would affect the card, but AMD is promising some energy efficiency breakthroughs, plus given how roomy the card is, the vent seems sufficient.Finally, information from ArabHardware.net suggests a pricing model on three of the first SKUs based on Cypress: HD 5870 2 GB, HD 5870 1 GB, and HD 5850 1 GB. All three use the same GPU and memory standard (GDDR5), but differ in clock speeds and GPU configurations. While HD 5870 sports 1600 stream processors, 80 TMUs, and 32 ROPs, HD 5850 has 1440 stream processors, 72 TMUs, and 32 ROPs. Although 32 ROPs puzzles us for a 256-bit wide memory interface, we suspect low-level design changes that make "32 ROPs" more of an effective count than an absolute count. While HD 5870 features over 800 MHz core clock and 5.20 GHz memory, its little sibling has over 700 MHz core clock and 4.40 GHz memory. Price points expected are US $449 for Radeon HD 5870 2 GB, $399 for HD 5870 1 GB, and $299 for HD 5850. AMD is expected to announce all three models on the coming 23rd. You'll be able to find them at your favourite computer store a little later, availability is a certainty by the time you're ready to buy Windows 7. AMD's newest products will be more than ready to squat under X-mas trees all over.

163 Comments on AMD Cypress ''Radeon HD 5870'' Stripped
It do draw 180 watts at times, just like 4890 which basicly use 163 watts average with 10 diffrent games.
that card was rated 190 W.
Lets all stop the speculations on powerconsumtion, and see what REVIEWS say, you guys missed whats more interesting than load powerconsumtion.
Idle! 23 W is a low figure, and should provide better powerbill savings than lower load powerconsumtion and higher idle (hd4xxx).
Many says:
HD5xxx is gonna be perfect if its near 4870-4890 load powerconsumtion and gtx260 idle consumtion!
I really dont care if i can hear the damn card without sound while im playing, as long as its idling i really dont wanna hear it, i guess people dont play without sound.
I do care about the sound myself while I'm playing, but I don't think that ANY card will ever be louder than my power supply anyway. I have never used one of those cards that do 50+ db on the reviews though, I usually choose the silent ones. Every card is silent in comparison to my power supply, it was silent but not anymore, I bent it's fan a bit while cleaning it from dust sadly. That's why I use headphones instead of my 5.1 setup most of the times until I replace it. But don't think the PS does a lot of noise. It's just that I paid a lot to have a noise free (clean sound) sound setup just to let something spoil it. Ey! You got the idea! :roll:
Hmm, runs quite well on 3* 1920x1200. I think it's only one Cypress board, as Eyefinity can't do CF atm...
- It says it's the same GPU; although the 5850 has less shaders etc.??? Maybe ATI GPUs are going the way AMD CPUs are... some fiddling in the BIOS and there you are, full 1600 shaders ;) a la Radeon 9800 series.
- What CPU, RAM and PSU does it need? I wonder if a quad is needed to fully unleash this...
- Ummm... I'm still fixated on the matter of turning a 5850 on a 5870 :)
Remains to see if the cores are laser-cut or just inactive... and I expect you guys to let us know first hand since it will be some time 'til I get my hands on a DirectX 11 card.
AMD needs to poach into Intel's market share. Hence it didn't bother fixing the faulty ACC microcode. It holds a healthy market position with GPUs. Will not let go of $100 with shoddy harvest methods.
I'm pretty damn sure the 5800 series will be locked at the advertised specs... but I'm hopeful for the best...
EDIT: It seems like a 4850 GPUs got somehow misplaced on the 4830 boards or something, not related to unlocking cores. The GPU-Z info is the same as the 4850 even the clocks. So guys who bought them I think just found out a better GPU in their computer. Oh well, who doesn't dream on such things...
Dual pc power&cooling 750W.
i HAD 3 4870, but sold two.
And a silverstone TJ07, which isnt very sound isolated to be honest.
The 4870's are rather quiet, you do hear them a little when i play crysis, Yes.
Nothing that ruins the game experience, hope the 5870 is in the same league :)
Can't wait :p
Sacrificing having my own computer for a while and just going to whack it into my parents system XD
