Because of the level of integration required by HBM2 memory, GP100 packages have to be fully assembled with their interposer and HBM2 ahead of time. Not explicitly said by the company (but is clear from the specifications) is that this is meant to be a salvage part for GP100. NVIDIA has previously offered multiple tiers/prices of high-end Tesla cards – though usually under different model numbers to make them easier to differentiate – so having multiple PCIe cards is not unusual for the company. The L2 cache, which is directly tied to the memory controllers, is also reduced from 4MB to 3MB. This brings the total memory capacity down to 12GB, and the total memory bandwidth down to 540GB/sec. The lower-end card ships with the same GPU clockspeeds and overall compute throughput, but it cuts the amount of memory and the memory bandwidth by 25%. It’s on this latter point that the lower-end version of the PCIe Tesla P100 further changes things. Clockspeeds haven’t been dialed back here at all, so it’s still 1.4Gbps HBM2 in a quad package configuration, allowing for 720GB/sec of bandwidth (both with and without ECC).

Meanwhile on the memory side of matters, the higher-end card ships with the full 16GB of HBM2 enabled. Shipping with the same TDP means that these PCIe cards can be used as drop-in replacements for older Tesla cards, since they have the same power and cooling requirements. The change in clockspeed is to accommodate the lower TDP of the PCIe card whereas the mezzanine cards are 300W, the PCIe cards are 250W, which is the same TDP as past generation Tesla PCIe cards. This puts theoretical throughput at 9.3 TFLOPs for FP32 and 4.7 TFLOPs for FP64, versus 10.6 TFLOPs and 5.3 TFLOPs respectively for the original P100. In this case we’re looking at the same 56-of-60 SMs enabled, only with a boost clock of 1.3GHz rather than the original P100’s 1.48GHz. The higher-end PCIe configuration is essentially a downclocked version of the original P100 on a PCIe card. NVIDIA will be shipping two versions of the PCIe Tesla P100. NVIDIA Tesla Family Specification Comparison However not every customer needs the features of NVLink or wants to build systems specifically for the mezzanine connector, and this is where the PCIe version of the card fleshes out the Tesla P100 lineup. The mezzanine connector marked a radical departure from traditional NVIDIA Tesla card designs, but also one that was necessary to facilitate NVIDIA’s high-speed point-to-point NVLink bus. The initial version of the P100 announced at the time was NVIDIA’s highest performing version, a 300W board using NVIDIA’s new mezzanine connector, and shipping with 56 of 60 SMs enabled.

Besides being a bigger-still GPU, P100 introduces a number of new features including larger caches, instruction level preemptive context switching, and double speed (packed) FP16 compute.
TESLA P100 FP64 SERIES
Based on NVIDIA’s new Pascal architecture and their 16nm GP100 GPU, Tesla P100 is a significant step up from the Tesla K/M series and their respective 28nm Kepler/Maxwell GPUs. We were first introduced to Tesla P100 back in April of this year, when NVIDIA announced it at their 2016 GPU Technology Conference. Starting things off this year is NVIDIA, who is taking to the show to announce the PCI Express version of the Tesla P100 accelerator. One of the two major supercomputing conferences for the year, ISC is commonly used as a backdrop for high performance processor announcements, and this year is no different. Kicking off this week in Frankfurt, Germany is the annual International Supercomputing Conference, better known as ISC.

Today, my kids and their peers have aged out of the fad thing (oldest approaching 30) but, those peers with younger siblings it's. I would not be caught dead at a Britney Spears concert then the fad that says t says "I'm in the know, I'm not a bling bling guy" will be the total absence of RGB. How about a smartphone for which I don't have to say "Let me call you back from a land-line" ? How about a phone that doesn't focus on form giving me the thickness of a slice of cheese and batterly life less than a day, and instead gives me a week of battery life, as my Treo 650 did more than 12 years ago ? Give it 3 months. With the younger generations allegedly being "tech savvy", this obvious bent towards from over function proves that "tech savvy" assumption blatantly wrong. This comes on the back of a video i just watched entitled "if this is what the new iPhone, looks like, Samsung is in trouble".
