I’ve decided to try a 4 GPU capable rig. Llamacpp runs rather poorly vs P40, no INT8 cores hurts it. 7 GFLOPS FP32 (float) = 11. 58 TFLOPS So with the p40 you lose the benefit of running LLM's and other AI's in FP16 in reasonable speeds. The performance of P40 at enforced FP16 is half of FP32 but something seems to happen where 2xFP16 is used because when I load FP16 models they work the same and still use FP16 memory footprint. For what it's worth, if you are looking at llama2 70b, you should be looking also at Mixtral-8x7b. RTX 2080 Ti is $1,199 vs. On Pascal cards like the Tesla P40 you need to force CUBLAS to use the older MMQ kernel instead of using the tensor kernels. Not sure where you get the idea the newer card is slower. Flash attention cannot be enabled on the M40 while the P40 cannot be overclocked. Main reason is due to the lack of tensor cores. Initially we were trying to resell them to the company we got them from, but after months of them being on the shelf, boss said if you want the hardware minus the disks, be my guest. If all you want to do is run 13B models without going crazy on context a 3060 will be better supported, if you want to run larger models that need twice the VRAM and you don't mind it being obsolete in a year or two the P40 can be interesting.

The Tesla P40 was an enthusiast-class professional graphics card by NVIDIA, launched on September 13th, 2016. witin a budget, a machine with a decent cpu (such as intel i5 or ryzen 5) and 8-16gb of ram could do the job for you. Got myself an old Tesla P40 Datacenter-GPU (GP102 like GTX1080-silicon but with 24GB ECC vram, 2016) for 200€ from ebay. You can just open the shroud and slap a 60mm fan on top or use one of the many 3D printed shroud designs alrea P-40 does not have hardware support for 4 bit calculation (unless someone develops port to run 4 bit x 2 on int8 cores/instruction set). Jul 27, 2023 · To partially answer my own question, the modified GPTQ that turboderp's working on for ExLlama v2 is looking really promising even down to 3 bits. Tesla V100 is $8,000+. However, the Tesla P40 specifically lacks FP16 support and thus runs FP16 at 1/64th the performance of other Tesla Pascal series GPUs 1&2: 2x Used Tesla P40 GPUs 3&4: 2x Used Tesla P100 Motherboard: Used Gigabyte C246M-WU4 CPU: Used Intel Xeon E-2286G 6-core (a real one, not ES/QS/etc) RAM: New 64GB DDR4 2666 Corsair Vengeance PSU: New Corsair RM1000x New SSD, mid tower, cooling, yadda yadda. ExLlamaV2 is kinda the hot thing for local LLMs and the P40 lacks support here. Works great with ExLlamaV2. g. I want to force model with FP32 in order to use maximum memory and fp32 is faster than FP16 on this card. What you can do is split the model into two parts. cpp. Cost on ebay is about $170 per card, add shipping, add tax, add cooling, add GPU cpu power cable, 16x riser cables. But 24gb of Vram is cool. I too was looking at the P40 to replace my old M40, until I looked at the fp16 speeds on the P40. If you want multiple GPU’s, 4x Tesla p40 seems the be the choice. Possibly because it supports int8 and that is somehow used on it using its higher CUDA 6. Technical City. P40 Cons: Apparently due to FP16 weirdness it doesn't perform as well as you'd expect for the applications I'm interested in. The V100s are performing well running Llama 3 70B at Q5 fully offloaded in VRAM. We Tesla P40 have really bad FP16 performance. Open menu Open navigation Go to Reddit Home. English . 76 tflops: fp64: 367. From a practical perspective, this means you won't realistically be able to use exllama if you're trying to split across to a P40 card. llama. 1). cpp the video card is only half loaded (judging by power consumption), but the speed of the 13B Q8 models is quite acceptable. FYI it's also possible to unblock the full 8GB on the P4 and Overclock it to run at 1500Mhz instead of the stock 800Mhz I'm considering Quadro P6000 and Tesla P40 to use for machine learning. The 22C/44T are still $250 (same as a P40) so not really worth it as it does not give extra options it seems. ) Tesla P40 GPU Accelerator PB-08338-001_v01 | ii . Although stock 2080 is more modern and faster, it is not a replacement for P40, due to much smaller RAM. Possibly slightly slower than a 1080 Ti due to ECC memory.

My guess is that if you have to use multiple cards, you’re gonna have a bad time. 8 11. This card can be found on ebay for less than $250. 58 TFLOPS FP32 (float) = 35. Honestly the biggest factor for me right now is probably the fact that the P40's chip was also built into consumer cards which in turn have been tested for all kinds of AI inference tasks - maybe the bad fp16 performance (GP100 vs. Full-precision LLama3 8b Instruct GGUF for inference on Tesla P40 and other 24 gb cards We would like to show you a description here but the site won’t allow us. If this is true then Nvidia are intentionally crippling FP16 on the Titan X/Xp/1080Ti because they use the same GPU (GP102). This is a misconception. I'm running CodeLlama 13b instruction model in kobold simultaneously with Stable Diffusion 1. no error but no speed up. 你得到答案了吗？ don't support. So total $725 for 74gb of extra Vram. Jan 31, 2014 · This makes the Tesla GPUs a better choice for larger installations. Sep 13, 2016 · For AI Training, NVIDIA offers the Tesla P100 solution with the fastest compute performance available to date, both FP16 and FP64. So Exllama performance is terrible. The server came with a 6C/6T E5-2603 v4, which is actually fine since I am running on the P40 mostly. The GP102 (Tesla P40 and NVIDIA Titan X), GP104 , and GP106 GPUs all support instructions that can perform integer dot products on 2- and4-element 8-bit vectors, with accumulation into a 32-bit integer. So, it's still a great evaluation speed when we're talking about $175 tesla p40's, but do be mindful that this is a thing. . cpp that improved performance. So Tesla P40 cards work out of the box with ooga, but they have to use an older bitsandbyes to maintain compatibility. I run the fp16 mode on P40 when used tensor RT and it can not speed up. Also, I think this is why Invoke AI does not recommend these cards TLDR: trying to determine if six P4 vs two P40 is better for 2U form factor. A full order of magnitude slower! I'd read that older Tesla GPUs are some of the top value picks when it comes to ML applications, but obviously with this level of performance that isn't the case at all. P40s can't use these. I've found some ways around it technically, but the 70b model at max context is where things got a bit slower. ASUS ESC4000 G3. The Tesla cards will be 5 times slower than that, 20 times slower than the 40 series. Sep 13, 2016 · Neural network training, which typically requires FP16 performance and a whole lot of horsepower, is handled by the likes of the Tesla P100 series, the only cards in NVIDIA’s lineup with a high Mar 11, 2019 · Note: Some models are configured to use fp16 by default, you would need to check if you can force int8 on them - if not just use fp32 (anything is faster than fp16 pipe on p40. This is Sep 2, 2021 · Tesla GPU系列P40不支持半精度(FP16)模型训练。因为它没有Tensor core。 训练bert非常慢，想要加速，了解到半精度混合训练，能提速一倍，研究了下混合精度，以及其对设备的要求。 Jun 20, 2016 · NVIDIA Tesla P40 vs NVIDIA Tesla P100 PCIe 16 GB. It’ll run 4 P40 right out of the box… I wager it’ll handle 4 x A100s as well. What I suspect happened is it uses more FP16 now because the tokens/s on my Tesla P40 got halved along with the power consumption and memory controller load. for storage, a ssd (even if on the smaller side) can afford you faster data retrieval. Stop talking about P40 please, at least until I can buy one more, as y'all are raising the prices 😂 Also don't talk about the P100 which is 16GB but double the bandwidth and offers 19TF of fp16 (vs 12TF of fp32 on the P40) this should keep up much better with a 3090 at the expense of 40GB total VRAM. I got a Tesla P4 for cheap like many others, and am not insane enough to run a loud rackmount case with proper airflow. IIRC 48gb vram (be it dual 3090s or dual tesla P40s) will allow for native 30B and 8-bit 65B models. I have two P100. In one system it's by itself. 4 iterations per second (~22 minutes per 512x512 image at the same settings). Also TurboDerp, as of current, has yet to implement any type of measures to circumvent Tesla P40's terrible fp16 performance (admitedly sort of a niche problem). VLLM requires hacking setup. In terms of FP32, P40 indeed is a little bit worse than the newer GPU like 2080Ti, but it has great FP16 performance, much better than many geforce cards like 2080Ti and 3090. Running on the Tesla M40, I get about 0. The GP102 (Tesla P40 and NVIDIA Titan X), GP104 (Tesla P4), and GP106 GPUs all support instructions that can perform integer dot products on 2- and4-element 8-bit vectors, with accumulation into a 32-bit integer. Therefore, you need to modify the registry. It's a pretty good combination, the P40 can generate 512x512 images in about 5 seconds, the 3080 is about 10x faster, I imagine the 3060 will see a similar improvement in generation. Getting two Nvidia Tesla P40 or P100 GPUs, along with a PCIe bifurcation card and a short riser cable and 3d-printing both a mounting solution that would place them at a standoff distance from the mobo, as well as an airduct that would funnel air from the front 140MM fan through both of them (and maybe a pull-fan at the exhaust). 179K subscribers in the LocalLLaMA community.
