NVIDIA GeForce GTX 980 has 2048 CUDA cores

Not 1920, not 2560, but 2048 CUDAs are powering the new flagship card from NVIDIA.
GeForce GTX 980 has 16 Streaming Multiprocessors Maxwell (SMM), which give us 2048 CUDA cores in total. For comparison, GTX 970 has only 13 SMMs (1664 CUDAs), so there’s a 384 CUDA difference between these two cards.
GeForce GTX 980 is advertised as GK104 replacement, it is much more power efficient and much more powerful than first Kepler processor.
We will cover 2nd Generation Maxwell in detail very soon. Maxwell GM204 has some very neat features for gamers.
This post was only meant to confirm there are 2048 CUDAs in 980, hence not the most detailed table below.
Game24? How bout’ GameOver.
Are you having a boring Sunday? Well if you do, then we bring you something interesting to see.
What you’re looking at is the new GeForce GTX 980. Today we are solely looking at the design. Specifications will be covered in our next post.
NVIDIA GeForce GTX 980 has been a mystery until now. The new flagship will adopt GeForce GTX TITAN/780/780Ti cooling solution. It is a blower type cooler capable of dissipating 250W of power. This time it will only have to deal with 180 Watts, leaving plenty of headroom for overclocking.
Now let’s take closer look at the card. First up, there are some cosmetic changes, like the one below.
However the biggest improvement can be seen on the back. NVIDIA has adopted TITAN Z backplate for its new flagship.
There is a removable part over power connectors. We do not know why yet.
GeForce GTX 980 has two 6pin power connectors. There is a space for another 8pin connector, but we are more than sure it is not necessary. It is said that GeForce GTX 980 will require only 180W, so PCI-E interface and two 6-pin connectors are more than enough.
The memory layout has of course changed, as we have modules with higher capacity. This particular sample is using Samsung K4G41325FC-HC28 4Gb (128Mx32) modules.
What pictures do not show is the new display output configuration. NVIDIA GeForce GTX 980 has five display outputs: DVI, HDMI, and three DisplayPorts. We heard that GTX 980 and 970 may feature HDMI 2.0 support, but we were unable to confirm it.
The power section has been redesigned. GTX 980 has 5 GPU phases (780 Ti had 6), but the VRM has been greatly improved.
Anyway, it’s late, so enough talking, have a look at the PCB, you can also see the new bracket (which looks similar to TITAN Z).
NVIDIA GeForce GTX 980 and GTX 970 Pricing Revealed from TechPOwerUp:
Apparently, NVIDIA is convinced that it has a pair of winners on its hands, with its upcoming GeForce GTX 980 and GTX 970 graphics cards, and is preparing to price them steeply. The GeForce GTX 980 is expected to start at US $599, nearly the same price as the GeForce GTX 780 Ti. The GTX 970, on the other hand, will start at US $399, danger-close to cannibalizing the GTX 780.
Across the brands, the GTX 980 is launching at the same pricing AMD's Radeon R9 290X launched at; and the GTX 970 at that of the R9 290. AMD's cards have since settled down to $449 for the R9 290X, and R9 290 at $350. Both the GTX 980 and GTX 970, will be available in non-reference board designs, although reference-design GTX 980 will dominate day-one reviews. Based on the 28 nm GM204 silicon, the GTX 980 features 2,048 CUDA cores, 128 TMUs, 32 ROPs; while the GTX 970 features 1,664 CUDA cores, and 104 TMUs. Both feature 256-bit wide memory interfaces, holding 4 GB of GDDR5 memory.
NVIDIA GeForce GTX 980 final specifications from VideoCardZ. Thanks to @Truth_Hurts_U
On September 19th, NVIDIA will finally reveal its new GeForce 900 series.
Two cards will be announced during a special event for gamers (Game24): GTX 980 and GTX 970.
While the GTX 970 is just a gap-filler, GeForce GTX 980 is much more – a proper new flagship card.
Introducing Maxwell GM204
First, let’s have a look at the new processor, the GM204. This is the first GPU based on ‘Second Generation Maxwell‘ architecture. When GM107 was announced, I think everyone was expecting GM2xx architecture to use smaller node, but unfortunately, we are still on 28nm fabrication node.
GeForce GTX 980 is equipped with full fat GM204, the 400 variant. This GPU has 16 Streaming Multiprocessors “Maxwell” (SMM). What you didn’t know, is that GM204 has 64 Raster Operating Units. Yes, GM204 has 64 ROPs, that’s more than Kepler GK110.
The GM204 has in fact, the same number of Texture Mapping Units (TMUs) — 128, but thanks to higher core clock, texture fillrate is actually higher.
There are 5.2 billion transistors packed into GM204, and the GPU has a die size of 398 mm2.
And for those wondering how large L2 Cache is, then the answer is: the same as GM107 — 2MB.
NVIDIA Maxwell GM204 has some cool features like Dynamic Super Resolution, which is basically new upscaling technology advertised as ‘4k Quality on a 1080p display’.
Other interesting technology is Third Generation Delta Color Compression. This technology will help increase memory efficiency, which is definitely required with 256b interface.
The final buzzword for you is Multi-Pixel Programmable Sampling, technology improving sample randomization, and reducing quantization artifacts.

GM204 is split into four Graphics Processing Clusters (GPCs). Each GPC has 4 SMMs. There are four 64b memory controllers. Large L2 Cache is accompanied by 64 ROPs.
NVIDIA GeForce GTX 980 Final Specifications
GeForce GTX 980 has 2048 CUDA cores, 128 TMUs and 64 ROPs. Card is equipped with 4GB GDDR5 memory and 256-bit interface. It has a bandwidth of GTX 770, which is 224 GB/s. By comparing it to Kepler parts, we notice that Maxwell-based graphics cards arrive with relatively higher clock speeds, GTX 980 has a base clock of 1126 MHz and boost clock of 1216 MHz.
The biggest news here is that GTX 980 has only a TDP of 165W. That’s amazing power reduction compared to 250W GK110.
Last but not least, I can now confirm that GeForce GTX 980 has HDMI 2.0 support. And if you somehow missed my previous news, GTX 980 has 5 display outputs: DVI-I, HDMI2.0 and three DisplayPorts 1.2 (not 1.3).
NVIDIA GeForce GTX 980 will be released on September 19th. Card is expected to cost around $599 USD (unconfirmed).
