    Renesas Electronics Collaborates with AMD to Accelerate Promotion of USB 3.0 Standard

    Renesas Technology Corp was always a separate company but signed merger with NEC Electronics last December 2009. Officially merged last month (April 2010) and new company is called Renesas Electronics. http://www2.renesas.com/news/en/archive/0912/1501.html?src=rss_ir_en NEC is still NEC. NEC...

    Scythe Releases Kama Flow 2, New Fan Series with EX-FDB Bearings

    the old kaze-juni series still seems to have the better specs (more airflow with less noise) For example the 120mm SY1225SL12M 1200rpm 24.00dBA 68.54CFM 0.26A http://www.scythe.co.jp/cooler/kaze-juni.html

    I will be leaving TPU!

    well it's april 2nd in Japan now, but I think it is still April 1st in Stuttgart. I guess I will see tomorrow morning. a little hope he will change his mind....

    looking more and more real. signed petition just in case it helps change his mind.

    I will be leaving TPU!

    If you ever wanted to get into bioinformatics and move to Japan, there is a fair amount of interest in GPU computing here. Still at the algorithm development stage, but that is probably the more interesting and challenging stage. Science is also one of these lower paid but doing it for the...

    NVIDIA GeForce GTX 480 Fermi

    Did you cleaned the grill, um I mean heatsink, before you sent it back? We should be on the look out for some future forum post where someone complains that Nvidia sent them a used card because there was egg in the creases of the heatsink....:laugh:

    NVIDIA GeForce GTX 480 Fermi

    I think one of the most interesting things about GTX470 GTX480 (Fermi) is 1) it does compete nicely with 5850 and 5870, but needs to "run hot" to do it. 2) but the architecture looks really clean and scalable into the future 3) the "problems" are heat and power (not architecture) and maybe...

    New Heaven's Benchmark will be version 2.0 not 1.1

    I second this idea. If the extreme tessellation mode appears to only increase work load without improving image quality, then wouldn't that indicate that extreme tessellation will never end up in games? why do extra work if it gives no benefit. If we want to test pure number crunching power...

    GeForce GTX 400 Series Clock Speeds and Other Details Surface

    Well last week Charlie at semiaccurate reported that the GTX480 has a TDP of 275watts. http://www.semiaccurate.com/2010/03/12/semiaccurate-wrong-about-nvidia-480gtx-power-use/ There are a huge amount of false leaks out there. We won't really know all the details until the official release...

    NVIDIA GeForce GTX 480 Reference Design Card Final Design Pictured

    you are right, but I was wishing. Most likely NV prices will be high, ATI will most likely not lower prices on the current 40nm 5xxx series at all since it costs so much to make the chips on TSMC's 40nm process. I am still hoping for a summer process shrink to GF 32nm for the evergreen family...

    NVIDIA GeForce GTX 480 Reference Design Card Final Design Pictured

    I know this is a major wish, but I really hope the 5850 drops to $200 and the 5870 to $300. That or ATI announces something interesting ... like say .... a process shrink to GlobalFoundaries 32nm SOI along with less heat, higher clocks and cheaper manufacturing costs. maybe....

    Sennheiser HD 800

    I agree. I am happy with my Stax Lamdba/SR303/SRM1-mk2, AKG K1000, and Senheiser HD580. I am much more interested in picking up an AKG K702 or Audio Technica AD700.

    Sennheiser HD 800

    audiophile headphones are a hobby for some just like high-end PCs are for most on this forum. There are some here with double or triple SLI GTX290 which costs more than these headphones. Someone just as easily say "damn $2000 for graphics cards, I am happy with my $100 4850 graphics card, that...

    Radeon HD 5890?

    One more possibility for the "5xxx refresh" might be Evergreen on SOI 32nm from GlobalFoundaries. Ok hear me out.... The reason I say this is that the AMD Llano "Fusion" has taped out acording to BSN. This is a 32nm SOI "silicon on insulator" chip. What is REALLY interesting about this...

    Radeon HD 5890?

    From the original image http://techreport.com/r.x/radeon-hd-4870/die-shot.jpg I have cut out one SIMD and resized to 300%. The unit between the Texture units (first two blocks on the left) and 4x4 SPs (on the right) has a different structure to the SPs. You labeled this as 2 extra SPs (9th...

    Radeon HD 5890?

    If you look closely at the die image, that 9th column's structure is different from the other shaders and is most likely the "thread sequencer unit" in the block diagram from this Anandtech http://www.anandtech.com/video/showdoc.aspx?i=3341&p=3
  17. jessicafae

    Radeon HD 5890?

    well you said 960sp and were certain of that. That 9th column is within a SIMD unit (row) and can not be disabled.

    Radeon HD 5890?

    ok show me the extra shaders on the RV770 die image.
  19. jessicafae

    Radeon HD 5890?

    Are you certain RV770 had 12 SIMD units and 960 physical SPs and all 4870s had 160 physical shaders disabled? Here is a die image of RV770. I count 10 SIMD units (10 rows of 4x4 shaders, just like RV790) meaning no "extra physical shaders which will never be used"

    Radeon HD 5890?

    hmm. I think you just confirmed that cypress really does have 2560 shaders and that the 1600sp variant (5870) is a harvested part.
  21. jessicafae

    Radeon HD 5890?

    I can not recall any ATI die where there was not a variant with all the shaders enabled. For example here is RV790 (4890) and it can be seen that the SIMD block has 10x16x5 = 800 shaders (10 rows) so there are not "extra physical shaders that will never be enabled" I know that lower spec...

    Radeon HD 5890?

    I don't know why no one has ever brought this up, but ATI never released an official die shot of cypress. They have only officially released architecture block diagrams. And the leaked die image (below from this post) actually has 2x16x16x5 shaders (2560sp, note the 16 rows on each side of 4x4...

    ASUS EAH 5830 DirectCU

    I think the point is more that if someone already owns a 4890 or 4870 or 2x4850 then they need comparison to the 5770, 5830 in order to decide if it is worthwhile to upgrade/change. In this case there is not sufficient performance improvement to justify the change. If one is moving from 46xx or...

    ASUS EAH 5830 DirectCU

    wow I think the 5830 shows how high the defect rate (and how bad the yields) are with the TSMC 40nm process. They almost had to disable half of the chip to get the 5830 (30% of the shaders are disabled and 50% of the ROPs). The 55nm 4830 only needed to disable 20% of the shaders (640/800) and...

    GLOBALFOUNDRIES and ARM Define the Standard for Mobile Technology Platform Innovation

    I agree, we should see a lot more ARM/linux based netbook class machines in 2011 with these 28nm chips. The high-performance process will be interesting to watch. http://www.tomshardware.com/news/ARM-Atom-Netbooks,7242.html Who knows, maybe there will be an ARM/ATI SOC in the not-to-distant...
