NVIDIA preparing GeForce GTX 980 Ti with 6GB VRAM, faster than Titan X

It seems like a given, but NVIDIA is preparing another VGA card for release in the very near future: the GeForce GTX 980 Ti. The GTX 980 Ti would be a cut down version of the GM200-powered Titan X, with 6GB framebuffer and it'll be around 10% faster than Titan X, too.

According to SweClockers the new GeForce GTX 980 Ti would be the flagship card that NVIDIA will push, versus the Titan X. One of the reason this is, in my opinion, is that the new GTX 980 Ti can have add-in-board (AIB) partners play with the PCB and cooling setup, something that can't be done on the Titan X.

 

This will allow for some huge overclocks on the GTX 980 Ti, and some very exotic cooling setups. We should expect NVIDIA to unveil the GeForce GTX 980 Ti sometime in the second half of the year, after AMD launch its Radeon R9 390X.

Most of AMD's Radeon Rx 300 series will reportedly be rebrands

It looks like AMD's Radeon 300 series is beginning to take better form, where we're learning that the new cards will be filled with a bunch of rebrands, something that has been discovered hiding in the Catalyst 15.3 Beta drivers. Here's the run down of what is found in the Catalyst 15.3 Beta drivers:

BFG trolls with the GeForce GTX Titan XXX with 24GB of RAM and 300W OC

An early April Fools joke is appearing online, so we're going to make it clear: this will probably not happen. But, OverclockersUK and BFG are teasing a new GeForce GTX Titan XXX, which has a huge 24GB of VRAM, double the framebuffer of the GeForce GTX Titan X, which has 12GB.

 

bfg-trolls-geforce-gtx-titan-xxx-24gb-ram-300w-oc_01

 

Most of the specs are identical to the reference GTX Titan X, except it has 24GB of VRAM and higher clock speeds. We have two 8-pin PCIe power connectors which use up to 300W of power in "300W OC mode" or 250W at its stock settings. The RAM has been overclocked to 8600MHz, up from 7000MHz on the reference card.

 

We have a Base Clock of 1268MHz and Boost Clock of 1493MHz, versus the 1002MHz and 1072MHz of the reference GTX Titan X. These overclocks are mammoth, but it would be very interesting to see this become a real card. The price? A huge $2400+, compared to the $999 pricing of the GeForce GTX Titan X.

 

The release of the card? Exclusive to OverclockersUK on April 1.

SK Hynix shows off HBM 2 wafer at NVIDIA's GTC 2015 event

GTC 2015 - We didn't expect to see HBM 2 shown off in person here at NVIDIA's GPU Technology Conference, but here we are - SK Hynix has a HBM 2 wafer on the show floor, and it's beautiful.

A closer shot of the wafer itself.

 

SK Hynix's HBM memory promises increased bandwidth, as well as lower power consumption compared to conventional DRAM found on current cards, such as GDDR5.

 

sk-hynix-shows-hbm-2-wafer-nvidias-gtc-2015-event_04

 

We haven't even got HBM1 out yet, but HBM2 is promising so much more. HBM1 will have 128GB/sec per 1Gbit chip, while HBM2 will offer double that, with 256GB/sec with 2Gbit chips. We are also going to see lower power consumption, with 1.2V for HBM1 and HBM2, compared to GDDR5 which uses 1.35 to 1.5V.

The next-gen Pascal-based GeForce could feature 32GB of VRAM

GTC 2015 - One of the things we didn't quite have the time to talk about yesterday was the 3D Memory and HBM 2.0 side of the upcoming Pascal architecture form NVIDIA. This architecture should find itself onto a new VGA card sometime in 2016, rocking a huge 32GB of VRAM.

 

next-gen-pascal-based-geforce-feature-32gb-hbm-2-vram_01

 

NVIDIA briefed the crowd at its GPU Technology Conference here in San Jose, California where they displayed a slide with the amount of VRAM per GPU architecture. We can see that Kepler in 2012, which the last flagship card based on Kepler was the GeForce GTX 780 and GTX Titan Black featuring 3GB and 6GB of RAM respectively, while the Maxwell architecture provides between 4GB (on the GTX 980) and 12GB (on the GTX Titan X) respectively. The slide teases that Pascal will feature 32GB of RAM, and Volta will rock up to 72GB of RAM in 2018.

 

The way NVIDIA will do this is thanks to SK Hynix's High Bandwidth Memory (HBM) which allows for four-layer stacks, which is also known as 4-Hi. This will come in 1GB and 2GB varieties, but eight-layer stacks will eventually arrive, which should see a huge increase in the amount of framebuffer on the next generation of GPUs.

 

next-gen-pascal-based-geforce-feature-32gb-hbm-2-vram_02

 

Not only will Pascal deliver more VRAM on the card, but it will have magnitudes more memory bandwidth. The Maxwell-based GeForce GTX Titan X has 336GB/sec of memory bandwidth from its 384-bit memory bus on its GDDR5 RAM, but the Pascal architecture will be capable of a huge 750GB/sec or more. This will be using a variety of technologies to achieve this lofty height of memory bandwidth, including mixed precision, 3D Memory and NVLink.

 

We should expect NVIDIA to talk more about Pascal later in the year, or GTC 2016 this time next year.

NVIDIA announces Digits Devbox, with the 'maximum GPU out of a plug'

GTC 2015 - NVIDIA has just unveiled the new Linux-based Digits Devbox which is not a mass production platform, but a PC that is built as the "world's fastest deskside deep learning system" priced at a huge $15,000.

Inside, you'll find four of the new Maxwell-powered GeForce GTX Titan X cards, which will super accelerate deep learning with its insane GPU capabilities. The system is built-to-order, where you have a direct contact at NVIDIA once you purchase the system to help you out. This isn't a gaming PC, but we're sure this system could probably run Crysis.

NVIDIA teases Pascal, its next-generation GPU with 3D Memory, NVLink

GTC 2015 - NVIDIA has just started providing many more details on its next generation GPU architecture, known as Pascal. Pascal is going to be a giant leap from Maxwell, where it will be "10x faster than Maxwell" according to co-founder and CEO of NVIDIA, Jen-Hsun Huang.

 

nvidia-teases-pascal-next-generation-gpu-3d-memory-nvlink_05

Pascal will feature NVLink and 3D Memory which will provide some impressive performance and bandwidth, where we can expect 3x the memory bandwidth of Maxwell, which is quite the leak. On top of that, we have 400% more mixed precision, but the Pascal architecture itself is a huge leap for NVIDIA, even compared to the already impressive Maxwell architecture.

 

nvidia-teases-pascal-next-generation-gpu-3d-memory-nvlink_07

We have NVLink which has 5x the bandwidth of PCI Express, which is quite the jump in terms of available bandwidth. NVLink will provide the ability of having 8 GPUs, up from the 4-way limit of SLI right now.

NVIDIA's GeForce GTX Titan X is super-powering deep learning

GTC 2015 - NVIDIA has just made its new GM200-powered GeForce GTX Titan X official at its GPU Technology Conference, but the company is really pushing the deep learning side of things.

 

nvidias-geforce-gtx-titan-super-powering-deep-learning_01

 

The new Maxwell-based GeForce GTX Titan X is capable of training AlexNet for deep learning, at magnitudes faster than previous GPUs like the Titan, Titan Black and even a 16-core Xeon CPU from Intel. The Xeon CPU with 16 cores takes 43 days to train AlexNet, but Titan X drags this down to just three days. Even the Titan Black sits at five days, while the Titan is at 6 days.

NVIDIA makes the GeForce GTX Titan X official at GTC 2015

GTC 2015 - NVIDIA has made its GeForce GTX Titan X official at the GPU Technology Conference in San Jose, based on the full GM200 core. The GeForce GTX Titan X packs quite the performance punch with 8 billion transistors and 12GB of VRAM.

 

nvidia-makes-geforce-gtx-titan-official-gtc-2015_04

 

The new GeForce GTX Titan X is the most powerful GPU from NVIDIA yet, with the full GM200 core compared to the 'cut down' GM204 that makes the GTX 980 tick. The new Titan X is a powerhouse VGA card, with 30-50% additional performance of the GTX 980, and in some cases, much more. That's without taking into consideration the 12GB of framebuffer, too.

 

We have 3072 CUDA cores, 7 TFlops of performance and the huge 12GB framebuffer. We will have more details on the Titan X shortly. NVIDIA has also announced a price of just $999.

Leaked: AMD Radeon R9 390X performance, 60% faster than Radeon R9 290X

Hours before NVIDIA takes the veil off of its GM200-based GeForce GTX Titan X at GTC 2015, there are leaked details on specifications and performance for AMD's upcoming Fiji-based Radeon R9 390X.

 

leaked-amd-radeon-r9-390x-performance-60-faster-290x_01

 

According to the latest leaks, the new Radeon R9 390X with HBM memory will be up to 60% faster than the Radeon R9 290X with its 4GB of GDDR5 RAM. The leaked specs see the Fiji XT model featuring 4096 stream processors, a 4096-bit memory bus with up to 8GB of HBM memory, something that will provide 600GB/sec+ of memory bandwidth.

 

leaked-amd-radeon-r9-390x-performance-60-faster-290x_02

 

Comparing this to the R9 290X, we have 8.6 TFlops of performance on the R9 390X, which is a huge leap on the 5.6 TFlops that the R9 290X is capable of. HBM is said to be "leaps ahead" when it comes to video memory technology, where we have "drastically increased power efficiency" compared to GDDR5, and so much more. The R9 390X has full support for DirectX 12 and Mantle, with "new dual-GPU modes with upcoming drivers" being teased, as well as an "immersive VR experience with AMD LiquidVR".

 

Then we have the interesting model: the Radeon R9 390X WCE, which will come with watercooling by default, something that reviewers like us will receive. We don't know if this model will make it to the public, but the R9 390X WCE is "designed for 4K & VR gaming" according to the leaked slides.
