LeakedTT: NVIDIA to skip 600-series, jump straight to GeForce GTX 780? Did I mention it is nearly twice as fast as the GTX 580?

This was mostly unexpected, but then again, AMD have been waving their big red flag all over the Internet in the last few days due to the leaked AMD Radeon HD 7970 performance and specs. Today, we have PCINLIFE leaking an NVIDIA slide, that shows the difference in performance between their current single-GPU hero, the GeForce GTX 580 versus the GeForce GTX 780.

 

Say what? GeForce GTX 780?? Not GTX 680? Yes!

The above slide shows the performance between the current GTX 580 and the next-gen Kepler-based GTX 780. The test bed is a Core i7-3960X, Windows 7 64-bit, 297-Series driver, 2560x1600 resolution with both AA and AF enabled. The GTX 780 is virtually twice as fast as the GTX 580 if the chart is correct.

LeakedTT: AMD Radeon HD 7970 specs, 30% faster than 6970, launches on December 22

As the launch of AMD's next-generation Radeon cards gets closer, we have some exciting leaked specs to share with you. From some leaked slides, the specs of AMD's first Graphics Core Next (GCN) chip, the Tahiti XT, which goes under the suave name of the AMD Radeon HD 7970, will sport 3GB of GDDR5 (and not the rumored XDR2 memory), 3.5 TFLOPS of power, 2048 stream processors, 384bit memory width at 5.5Gbps, total load consumption of up to 300W and an less than 3W for idle.

 

leakedtt_amd_radeon_hd_7970_specs_30_faster_than_6970_launches_on_december_22_29

 

Display outputs include 1 x DVI, 2 x miniDisplayPort and HDMI, in terms of power connectors, it should have one 8-pin and one 6-pin. If these specs are true, we should expect the single-GPU Radeon HD 7970 to keep up with, and most likely beat in some games, the dual-GPU Radeon HD 6990 and NVIDIA GeForce GTX 590. It seems to be about 30-percent faster than the single-GPU Radeon HD 6970.

 

Once some great drivers are released for it, we should see more performance sucked out of the new cards. Two of these should see a game like Battlefield 3 run at Ultra quality, 1920x1080 at 120Hz absolutely maxed out with AA/AF at 120fps minimum, or 2560x1xx0 at 60Hz, minimum 60fps.

AMD's Tahiti Pro, HD 7950 cards, don't need to be reference design from day one

AMD have changed gears when it comes to their GCN launch on January 9, as most launches have the GPU manufacturer forcing AIBs to make cards based on the reference designs for at least the first 3 months after release.

 

This is good for AMD or NVIDIA, but for manufacturers, its hard to make your reference card stand out from the crowd. At launch, the cards are all pretty much the same thing and its only months later do we see some DirectCU models from ASUS, and TwinFrozr cards from MSI, etc.

But, AMD are unleashing their Tahiti Pro cards from the shackles of reference city... and SemiAccurate have heard from multiple sources that the HD 7970 will be able to sport non-reference designs from day one.

 

This will be a great thing for the launch of the HD 7000-series AMD cards, and their multiple AIB partners.

Why should you care about January 9, 2012? The AMD Radeon HD 7900 series launches then, that's why

Quick nugget here, AMD's Radeon HD 7000 series are set to launch on January 9, 2012 according to reliable market sources that DonanimHaber spoke with.

 

why_should_you_care_about_january_9_2012_the_amd_radeon_hd_7900_series_launches_then_that_s_why_05

 

AMD is expected to unveil two SKUs, the Radeon HD 7970 and Radeon HD 7950. This cards are based on AMD's new GCN, Graphics Core Next, and on a 28nm-based "Tahiti" silicon, which is a completely redesigned architecture.

 

January 9, January 9, January 9. It's nearly here.

RumorTT: AMD Tahiti GPU details

This post comes inclusive of many grains of salt, but the first leaks on AMD's Radeon HD 7970 are here. The GPU is said to be released on January 10, 2012, where our VGA editor has promised me after he's done he's going to send me all of our samples, right Shane? ;)

 

rumortt_amd_tahiti_gpu_details_24

 

Onto the rumor, 3DCenter have a compiled list of specifications for "Tahiti", from various sources and bits and pieces of info from here and there:

 

4.50 billion transistors, die-area of 380 mm², built on TSMC 28 nm process

Advanced GCN 1D architecture

2048 1D processing cores

128 TMUs, 48 ROPs

384-bit wide GDDR5 memory interface, memory clock slightly below 1 GHz, target bandwidth of 240~264 GB/s

Spotted: AMD Radeon HD 7000-Series cards

AMD's next-generation high-end graphics card has been spotted, with images making their way onto the Internet. The new boards are marked as "Tahiti" and are believed to be the top-of-the-line single-GPU cards from AMD. This should be what the Radeon HD 7900-Series will eventually be.

 

spotted_amd_radeon_hd_7000_series_cards_1

 

The card, as you can see in the picture above, is quite long, roughly the same length as AMD's current Radeon HD 6970. It sports twelve GDDR5 memory chips, which means they use a 384-bit memory bus. It also includes two 8-pin PCI Express power connectors, which should give it up to 375W of power to suck down. The card, however, is powered by the SIG-approved 6-pin plus 8-pin config, which uses up to 300W of power.

 

It shouldn't be long until we have more concrete info, but generally, when there are leaks like this, the real things aren't far behind.

Zalman to enter the GPU market

This is a bit unexpected, but a good move for Zalman. They have just announced their entry into the GPU market with the shipping of Zalman-branded GPUs to start shipping on December 13.

 

zalman_to_enter_the_gpu_market_04

 

Zalman's first entry will be AMD Radeon HD 6000 Series GPUs, in three different models: Zalman HD6870-H , H-Zalman HD6850 and HD6770 Zalman-H. As you can tell from the model numbers, they are HD 6870, HD 6850 and HD 6770 GPUs. Nothing high-end yet, but I'm sure Zalman are just putting their toes into the water, for now.

RumorTT: AMD Radeon HD 7900 Series to debut at $449/$549

Juicy one today, folks! It is rumored that AMD's flagship single-GPU graphics card will hit a US$549 price, with the slower model having a price tag of $449.

 

rumortt_amd_radeon_hd_7900_series_to_debut_at_449_549_1

 

Remember, that this is just a rumor and nothing is guaranteed, but it gives us a peak into what we could expect when the cards launch. Right now, the names being thrown around are the AMD Radeon HD 7970 and Radeon HD 7950, just like the previous variants of cards in the 6000 Series. The pricing is reportedly coming from AMD and not card partners.

 

We're expecting an early January shipping estimate, and should hopefully hear some more news on the subject soon. Is it too early to wish for two of these puppies? I'll take CrossFireX 7970's, thanks.

Radeon HD 7000 Series to be unveiled on December 5, get your red flag and join the red team party

To tell you the truth, I've been holding back my excitement on AMD's new GPUs for a while now. I was a huge fan of the HD 5000-Series, it just completely outperformed Fermi in virtually every way. Sure, it wasn't the fastest in every test, but it had great temps, great overclockability, great noise levels, and to me, was a better card to launch onto the market than the GTX 400-Series.

 

radeon_hd_7000_series_to_be_unveiled_on_december_5_get_your_red_flag_and_join_the_red_team_party_4

 

But, now we have AMD's first true new graphics architecture since the HD 2000-Series. Dubbed Graphics Core Next, or GCN, the new Radeon HD 7000-Series will be the first to feature the new technology, which is set to have a much bigger focus on GPGPU functionality than any ATI or AMD GPU previously, which should at least keep up with NVIDIA's CUDA, or beat it.

PCIe 4.0 to arrive 2014-2015, brings 16GT/s speeds

PCIe 3.0 is barely here and rumblings of PCIe 4.0 is coming through the cracks of the Internet tubes. PCI-SIG, who are responsible for developing the PCI Express spec, have listed some preliminary details about PCIe 4.0.

 

pcie_4_0_to_arrive_2014_2015_brings_16gt_s_speeds_1

 

PCI-SIG says that they've decided on a transfer rate of 16GT/sec for the next-generation PCIe technology, with a study showing that 16GT/sec can be achieved over copper wires, at roughly the same power levels of PCIe 3.0, using chips fabbed with "mainstream silicon process technology".

 

PCIe 4.0 will be backward compatible with older PCIe devices, and vica versa. PCI-SIG haven't mentioned which encoding scheme the new standard will use, so assuming it uses the same 128b/130b system as PCIe 3.0, a 16GT/sec peak transfer rate would translate into per-late, per-direction bandwitch of just under 2GB/sec, a two-fold increase over the PCIe 3.0 standard, and nearly four times as fast as PCIe 2.0. We'd be looking at 31.5GB/sec per direction for a PCIe 4.0 x16 slot.
