This seems to be estimating based on memory bandwidth / size of model, which is a really good estimate for dense models, but MoE models like GPT-OSS-20b don't involve the entire model for every token, so they can produce more tokens/second on the same hardware. GPT-OSS-20B has 3.6B active parameters, so it should perform similarly to a 3-4B dense model, while requiring enough VRAM to fit the whole 20B model. (In term…

While your remark is valid, there's two small inaccuracies here: > GPT-OSS-20B has 3.6B active parameters, so it should perform similarly to a 3-4B dense model, while requiring enough VRAM to fit the whole 20B model. First, the token generation speed is going to be comparable, but not the prefil speed (context processing is going to be much slower on a big MoE than on a small dense model). Second, without speculative…

So, this is all true, but this calculation isn't that nuanced. It's trying to get you into a ballpark range, and based on my usage on my real hardware (if I put in my specs, since it's not in their hardware list), the results are fairly close to my real experience if I compensate for the issue where it's calculating based on total params instead of active.

So by doing so, this calculator is telling you that you should be running entirely dense models, and sparse MoE models that maybe both faster and perform better are not recommended.

I have spent a HUGE amount of time the last two years experimenting with local models. A few lessons learned: 1. small models like the new qwen3.5:9b can be fantastic for local tool use, information extraction, and many other embedded applications. 2. For coding tools, just use Google Antigravity and gemini-cli, or, Anthropic Claude, or... Now to be clear, I have spent perhaps 100 hours in the last year configuring l…

I'd love to know how you fit smaller models into your workflow. I have an M4 Macbook Pro w/ 128GB RAM and while I have toyed with some models via ollama, I haven't really found a nice workflow for them yet.

I use Raycast and connect it to LM Studio to run text clean up and summaries often. The models are small enough I keep them in memory more often than not

Cool thing! A couple suggestions: 1. I have an M3 Ultra with 256GB of memory, but the options list only goes up to 192GB. The M3 Ultra supports up to 512GB. 2. It'd be great if I could flip this around and choose a model, and then see the performance for all the different processors. Would help making buying decisions!

Unfortunately, Apple retired the 512GiB models.

I agree, and I even started my response expressing my agreement with the whole point.

But since this is a tech forum, I assumed some people would be interested by the correction on the details that were wrong.

Is it correct that there's zero improvement in performance between M4 (+Pro/Max) and M5 (+Pro/Max) the data looks identical. Also the memory does not seem to improve performance on larger models when I thought it would have? Love the idea though! EDIT: Okay the whole thing is nonsense and just some rough guesswork or asking an LLM to estimate the values. You should have real data (I'm sure people here can help) and p…

From the video: 4.4k is "almost" 4x times 1.8k because 4.4k has "number 4" in the beginning, and the other one - number 1.

For the lazy: that's less then 3x: 1.8 * 3 = 5.4

Sure, but those already sold still exist.

From my personal testing, running various agentic tasks with a bunch of tool calls on an M4 Max 128GB, I've found that running quantized versions of larger models to produce the best results which this site completely ignores.

Currently, Nemotron 3 Super using Unsloth's UD Q4_K_XL quant is running nearly everything I do locally (replacing Qwen3.5 122b)
