NVIDIA roadmap: Maxwell only in 2014, no 780 before March 2013 likely

NVIDIA has had to push back its launch schedule due to troubles with the manufacturing processes. Originally, Kepler was supposed to launch in 2011, however, it is still being launched to this day and we've almost hit 2013. No new architecture will be produced until Maxwell in 2014.

Maxwell is an interesting animal. It will be a 20nm chip, which isn't a big deal. However, it is being designed so that it can be manufactured at GlobalFoundries, IBM, Samsung and TSMC. This should allow NVIDIA to ensure a large enough supply, or make a change if one of the fabs is having process issues.

 

The GTX 700 series should be a similar launch schedule to what has so far occurred with the GTX 600 series. This means we won't see anything until March 2013 or later. But the good news is that the new chip should between 25-30% higher performance and power efficiency. The Kepler refresh will have to compete with AMD's Sea Islands, so the real battle will take place in 2014 with Maxwell taking on Sea Islands.

PowerCooler unveils Devil 13 HD7990, only dual Tahiti in world

It's about time that someone went and made a 7990. We've been hearing that AMD has them coming for a long time now, but they have failed to deliver. That is, until today. PowerCooler has announced the world's first dual-Tahiti GPU and is calling it the 7990. Does this mean that we may finally start seeing them from other manufacturers?

 

TweakTown image news/2/5/25468_1_powercooler_unveils_devil_13_hd7990_only_dual_tahiti_in_world.jpg

 

For right now, PowerCooler is billing this card as the first and only 7990 in the world. The specifications are pretty beefy and really provide what everyone was expecting. The Devil 13 HD7990 has default settings at 925MHz engine clocks and 1375MHz memory clocks and sports 6GB of GDDR5.

 

Solidly-Built Design

The Devil 13 HD7990 is built with high efficiency thermal solution and solid components onboard. With trio fans and 10pcs U-shape heat pipes, maximizing the heat dissipated ability to cool down the Devil 13 board. Also, it includes 12+2+2 phases, digital PWM, super cap, UHB and PowerIRstage-all these platinum power kit enhances stability and reliability voltage for GPU with minimum conduction losses and lower temperatures at load, delivering the steadiest and most secure power to boost for performance.

NVIDIA launches their GeForce GTX 660 for OEMs

NVIDIA have reportedly released their GeForce GTX 660 GPU to the OEM market, and just like its bigger brother, the GeForce GTX 660 Ti, it sports the same GK104 core. But, it features just 6 SMX units enabled for a grand total of 1152 CUDA cores, as well as 96 texture units.

 

TweakTown image news/2/5/25436_07_nvidia_launches_their_geforce_gtx_660_for_oems.jpg

 

This is down from the Ti's 1344 CUDA cores, and 112 texture units. Frequencies have also received a bit of a snip, clocking in at 823MHz core, with an 888MHz boost clock, and 5,800MHz memory. The GTX 660 should arrive on OEM doorsteps with 1.5GB and 3GB GDDR5 configurations, a 192-bit memory bus, which should offer a maximum bandwidth of 134GB/s. This isn't bad considering the 660 Ti sports 144GB/s memory bandwidth.

 

The GTX 660 OEM should provide around 75% of the performance that its bigger brother does, but with lower performance brings a lower TDP, of just 130W. This allows NVIDIA to give the GTX 660 a single 6-pin PCIe connector. It will still include the usual four-display output configuration, featuring two dual-link DVI-I connectors, HDMI 1.4a, and a DisplayPort 1.2 socket.

AMD drops prices on high-end cards again

If you're looking to buy a new AMD graphics card, the time could not be better. AMD has again dropped prices on its high-end cards so that they are more competitive with NVIDIA's latest offering. With the NVIDIA GTX 660 Ti finally outed by the company, AMD wants to position its cards in places where they can compete.

 

TweakTown image news/2/5/25383_1_amd_drops_prices_on_high_end_cards_again.jpg

 

The street prices have dropped accordingly:

 

  • 1GB 7850 down $40 to $190
  • 2GB 7850 down $40 to $210
  • 2GB 7870 down $50 to $250
  • 3GB 7950 down $30 to $320

 

The 7970 does not see a price drop in this latest round, the both the 78XX and 7950 have had their prices lowered. The 3GB 7950 price drop brings its price down to a level similar to the GTX 660. In tests, a 2GB 7950 and 660 Ti were about 50/50. The 3GB version will likely pull out a couple of extra wins, and with the new pricing, should win business.

 

The price drops range from 10-20 percent, which are respectable discounts. These cheaper prices are the result of healthy competition, and while this might be a bit off topic, it needs to be said: this is why AMD needs to hang in the market against both NVIDIA and Intel. Better products (Kepler) and cheaper prices are sure to come because of it.

Sapphire 6GB 7970 Toxic cards are not cancelled

Contrary to rumors flying around the internet, Sapphire has not cancelled the 6GB 7970 Toxic graphics card they produce. It seems that because one major reseller put "discontinued" instead of "out-of-stock", or something similar, enthusiasts freaked out that they wouldn't be able to get the super fast card.

 

TweakTown image news/2/5/25311_1_sapphire_6gb_7970_toxic_cards_are_not_cancelled.jpg

 

At Gamescon, however, Sapphire has a large booth and sitting right in the middle as the pride and joy of the booth was the 6GB 7970 Toxic card. KitGuru asked Bill Donnelly for a little more information regarding the rumor flying around the web. The short answer? It's not discontinued, just facing production constraints.

 

Production on a card like this will always be limited, because of the tight selection process that every component needs to go though. To ensure that the clocks are stable at the levels our engineers have set for the top end Toxic cards, you will always be limited in terms of how many cards than make at once.

We think the rumour started when all of the cards made so far, sold out in every store that was carrying them across the globe. In almost every case, the resellers put a message saying 'Temporarily out of stock' or 'Pre-order only', but one of the largest resellers showed 'Discontinued' instead. And that caused a bit of a panic among enthusiasts who really wanted one.

 

Production is supposedly running smoothly and cards should start to become available again soon.

AMD announces updated HD 7950 featuring higher clocks and Boost

The red camp fires back. AMD has just announced an updated version of the 7950 in the same vein as the 7970 GHz edition update. What this means is that the card is getting faster base clocks as well as a new feature that boosts the core clock when the TDP isn't fully loaded. With AMD and NVIDIA nearly matched on performance and AMD losing in power efficiency, they've decided to go for the best performance-per-dollar.

 

TweakTown image news/2/5/25292_1_amd_announces_updated_hd_7950_featuring_higher_clocks_and_boost.jpg

 

So, aside from throwing power consumption out the window, what else have they changed? Not much really. The new base clock is up to 850MHz from the original 800MHz. Boost clock speeds allow the clock speed to jump to 925MHz. The reason power usage will jump is they have increased the core voltage to support these speeds.

 

With the 7970, it wasn't too bad as they had top bin parts. With the 7950, they are dealing with either broken chips or chips that wouldn't hit clock speed requirements. Because of this, AMD is using 1.25v which is higher than the 7970GHzE's 1.218v. It will be interesting to see how this increase affects benchmark results.

 

The card will launch with an identical name: HD 7950. The upgrade is a BIOS and driver change so all the board partners have to do is update their BIOS and re-qualify them. Once done, the physically same cards will begin shipping using the same name which could easily cause confusion. Way to go AMD!

RumorTT: NVIDIA GTX 650 specifications and launch date leaked

NVIDIA is having lots of trouble with the launch of the Kepler series. It seems as though information about every single card leaked out before the actual card was released. We previously told you about the GTX 660 Ti specifications and launch date, and have now provided a review for your viewing pleasure.

 

TweakTown image news/2/5/25091_1_rumortt_nvidia_gtx_650_specifications_and_launch_date_leaked.jpg

 

This time we bring news of the GTX 650, a new card that will be aimed at the sub-$200 market and launched in time for back-to-school shopping. It's important for NVIDIA to get a Kepler card into this price range as AMD completely controls that segment of the market right now. This market segment is also where most of the money is made.

 

The GTX 650 is rumored to launch on September 17 and will be packing a chip based on the 28 nm GK107 ASIC, which is based upon Kepler. The chip will utilize 384 CUDA cores, a 128-bit memory bus, and 1GB of memory. A quick guess at performance based upon CUDA core count would put the card competing with the AMD 7770.

GeForce GTX 660 Ti, 650 launch will see the GTX 560, 550 series discontinued shortly beforehand

According to a report from DonanimHaber, the launch of the GeForce GTX 660 Ti, GTX 660 and GTX 650 from NVIDIA will see the discontinuation of the GTX 560 and 550 shortly before the launch itself.

 

TweakTown image news/2/5/25064_06_geforce_gtx_660_ti_650_launch_will_see_the_gtx_560_550_series_discontinued_shortly_beforehand.jpg

 

This is not usual, but when you start seeing the stock dry up on the GTX 560 and 550, you'll know its nearly 660, 650 time. So if you're looking at grabbing a new GeForce GTX 560 or 550, we would suggest waiting it out for a little bit.

 

The new 660, 650 GPUs are expected sometime in August-September, so if you're content with your system now and can just hold out for a little bit longer, it might pay off. You could also grab a GTX 560 or 550 cheap if someone is moving on up, too.

RumorTT: NVIDIA to launch mid-range GeForce GT 660 Ti on August 16

SweOverclockers is reporting that NVIDIA are set to launch their mid-range GPU, the GeForce GTX 660 Ti on August 16. We've had a few previous posts on this, but the date is getting closer and closer.

 

TweakTown image news/2/5/25059_10_rumortt_nvidia_to_launch_mid_range_geforce_gt_660_ti_on_august_16.jpg

 

August 16 is just over a fortnight away, remember. NVIDIA's GeForce GTX 660 Ti is based on NVIDIA's GK104 core, which is the same core that is baked into each GTX 670.

 

It will sport 1344 stream processors, a memory interface of 192-bit, 2GB of GDDR5 memory, and core/boost/memory frequencies of 915MHz/980MHz and 6008MHz, respectively. TDP comes in at 150W, 20W less than the higher-end GTX 670 GPU.

AMD Radeon HD 7990 6GB is on its way, will arrive with four 6-pin PCIe connectors, 6 display outputs

AMD's elusive dual-GPU "New Zealand" Radeon HD 7990 has been hiding in the shadows for quite a while now, with the last time the card getting spotted was at the AMD Fusion Developer Summit in Bellevue, WA.

 

TweakTown image news/2/5/25051_01_amd_radeon_hd_7990_6gb_is_on_its_way_will_arrive_with_four_6_pin_pcie_connectors_6_display_outputs.jpg

 

According to a piece from VR-Zone, AMD have communicated to its partners that the HD 7990 would be ready in Q3 of this year, with a sampling date of June, which then led to a slip into July. The latest information comes from "confidential sources" who told VR-Zone that the boards will be coming in late-August at the earliest.

 

Considering NVIDIA have been enjoying the dual-GPU game with their GEFORCE GTX 690, AMD are considerably late to the party. The new HD 7990 is said to come with a very unique power system, consisting of four 6-pin PCIe connectors which will replace the usual dual 8-pin connector. These four 6-pin connectors give the card a multiphase power regulation, which is divided into three groups. The major groups are made up from Tahiti XT, 3GB GDDR5 memory per core (clocking in at 1.5GHz) and finally, the PLX PCIe 3.0 controller.
