RV740 i GT216 u 40nm

[Northwood]

AMD currently has RV740 cards running with 900Hz GDDR5 (that's 3600MHz effectively) in the lab...The RV740 silicon is A11 revision, board is B507/895 and the GDDR5 is Qimonda/IDGV1G-05A1F1C-40X.

RV740 is 40nm version of RV770LE with 640 stream processors. Its memory interface is reduced to 128bit by 50%, which is the same as that of RV730. But just as RV770XT (Radeon HD4870), RV740 also equips high-performance GDDR5. Because of 128bit memory bandwidth, RV740 only has 8 Render Back-Ends. (Note: there is an error in the chart from VR-Zone and we have corrected it).

Shintai is only speculating on the pin count dynamics for RV770/RV740, I would not take what he says literally. According to that kind of logic, handheld chips would never be nearly pad limited, yet they can be.

RV740 is a direct competitor to GT216: 512MiB 128-bit 1.8GHz+ GDDR5/16ROPs vs 768MiB 192-bit 1.2GHz GDDR3/12ROPs (and maybe 384MiB for OEMs?) - I don't know the TMU/ALU specs of either however, but ]RV730;RV770] and ]G94;GT200[ seems like a fair bet to me before considering clock speeds; the reason why I say GT200[ instead of G92] is that the absolute maximum I would be willing to seriously consider for GT216 is 32TMUs/160SPs.

Either way RV740 will be a very exciting chip most likely. While it could theoretically be a shrunk RV730 (hey, it could be a shrunk RV250 too!) that makes no practical sense, and I would not exclude the possibility it manages to achieve HD4850-level performance when paired with >2GHz GDDR5. So 2009 will be a very exciting year for 3D - and if I have my way, an even more exciting year for Beyond3D!

EDIT: Since VR-Zone/Expreview linked this post, two quick comments: 1) Once again the TMU/ALU specs are speculation, only take the memory config/ROP specs seriously. 2) 32 TMUs/160 SPs represents 40 SPs (5 "multiprocessors", each 8-wide) per "cluster". As I said in another post, I would *guess* anything from 24 TMUs/72 SPs to 32 TMUs/160 SPs is plausible. 3) What's up with linking to people's brain dumps on forums, even if they include a tiny leak along with all the rest?

GT216 will feature 192-bit memory interface and 768MB capacity. It adopts GDDR3, working at 1.2GHz (2.4GHz data rate). Probably there will be a 384MB version of GT216. No words yet on the number of stream processors...(The original text says GT216 will equip 160SP/32TMU, but considering the structure of GT200, 160SPs sounds impossible. GT200 contains 10 groups of TPC, and each TPC has 24 SPs. For instance, GT280 has 10 groups of TPC, GT260-192 has 8 groups, GT216-216 has 9 and GT216 might have 7).

40nm product is something great to expect. Both RV740 and GT216 are highly cost effective. We will continue to follow the next round of mainstream GPU battle.

mozda oko 100$?
