Maxwell Geforce GTX 870 Specifications and Benchmarks Leak Out


Hey folks, looks like the leak period of the Maxwell Geforce 800 Series has finally started because specifications and benchmarks of the GTX 870 have leaked out. Even though the leak comes from a source (Coolaler.com) that has leaked authentic information in the past, I would still recommend just the tiniest pinch of salt just in case.

Geforce GTX 870 Specs and Performance Leaked – 1664 CUDA Cores, 4GB GDDR5, 256Bit BUS and 4GB GDDR5

The entire leak consists of a couple of screen shots and at close inspection everything appears to be legit with not a hair out of place. As expected, the GPU core, which is GM204, is not properly recognized and the name detected shows Nvidia’s internal nomenclature. I ran the name “Nvidia 17D-20″ in a few databases but it didn’t net me anything else. This probably the engineering sample of the 870 and the code allocated to the GPU is 13C2. I am guessing that the 13 Stands for 13 SMMs and C2 stands for Consumer Chip no. 2. I am assuming the actual flagship will be named either 16C2 or 17C2 depending on the amount of Streaming Multiprocessor Maxwells (SMMs). A lot of other specs are not properly recognized and this is to be expected since there is no way that the GPU-Z tool has been updated to support Maxwell GPUs yet. The screen shots not only show the specifications but also reveal the 3D Mark Extreme and Performance scores as well, which is great because it allows us to rank the GPU among Nvidia’s existing cards. Since they are using an i7-4820K we can assume no CPU Bottleneck. Without any further ado, here are the complete specs of the high end Geforce GTX 870:

Now there is some pretty interesting information about this card. The 3d Mark performance benchmark of the GTX 870 is 11,919 and the extreme score is 4625. Now the GTX 780 scores around that point (4625) so any fears of the Maxwell series actually being weaker than its predecessor should be allayed. If the GTX 870 can score around the GTX 780 then the 880 should score more than the 780 Ti. The specs listed show 1664 CUDA Cores, which means that we are looking at a grand total of 13 SMMs (128 Cores per SMM, 1664/128 = 13). Following the previous generation trend, the Maxwell flagship should have 17 SMMs with a CUDA Core count of 2170 respectively. Basically, you should expect an SMM value of 14 – 17. I Will be really surprised if it goes any higher. The Pixel Fillrate appears to be 33.6 GPixels per second and the Texture Fillrate is 145 GPixels per second. In comparison the values of the 770 were 33.5 and 134 respectively. The bandwidth is 224 GB/s which is to be expected since the card has a 256 Bit Interface. Another interesting thing is that the memory used belongs to Samsung and not Hynix. So there you go folks, the first authentic looking leak regarding the Geforce GTX 870 Maxwell.

GTX 880/870 Due OCT/NOV!

Recently there has been a lot of news surrounding Nvidia’s GTX 880 GPU based on the next generation Maxwell architecture. We found through shipping details that the card will feature a 256 bit bus as compared to 256 or 512bit. The details received only specifying a high end Maxwell GM204 housing a 256 bit wide bus. Well folks at Sweclockers.com have sent us something very interesting. They have reportedly received details regarding the release dates of Nvidia’s desktop GeForce GTX 800 series. The launch is expected to take place in the fourth quarter this year.

Nvidia GeForce GTX 880 and GTX 870 Now Expected To Arrive Sometime Between October-December

Sweclockers is reporting that Nvidia’s GeForce GTX 880 and GTX 870 are now expected to be with us somewhere around the fourth quarter this year. This places the arrival schedule for the desktop GPUs in the period between October to December. The knowledge comes to the website from partner manufacturers of Nvidia. This upcoming launch of the cards will now mark the starting of the 800 series of desktop GPUs. Of course, the GTX 800 will be based on second generation Maxwell architecture. In addition, the new model series is still to be based on the 28 nm manufacturing technology. This is because even though TSMC has begun volume production on the 20nm node for everyone, the process is facing maturation problems for high performance ASICs like the GM204, but this is expected to start from sometime next year. In addition, it has also been learnt that Nvidia has canceled the production of GM100 chips and is now focusing completely on GM200 instead. These GPUs are still using the 28nm fabrication process.
I think we can now safely conclude that 20nm GPUs will come in 2015. This series is to become the Intermediary GPUs that we have been talking about for a long time. It is possible that one or two GPUs in the Geforce 800 Series lineup are 20nm but that is a long shot and will only happen in mid-late 2015. Another thing to add is that this second generation of Maxwell Architecture is speculated to feature ARM cores which could be a potential game changer. So 28nm Maxwell is coming, possibly with ARM cores but 20nm remains as far away as ever.
