User reports Llama 3.1 8B at 44.1 t/s generation and 892.5 t/s prompt processing on a Minisforum MS-S1 MAX with an AMD Ryzen AI Max+ 395 and integrated Radeon 8060S. Setup is llama.cpp build 7642 with the Q4_K_M GGUF, flash attention off, integer dot product disabled, 99 layers offloaded to one Vulkan0 device, and 64G of system RAM allocated to the GPU. The figures are separate llama-bench PP512 and TG128 phases, not one 512-input/128-output request, with 4.58 GiB model size and f16 K/V cache at prepared depth 0.

User reports Llama 3.1 70B at 14.9 t/s on a Mac Studio with an M3 Ultra and 512 GB of unified memory. Setup is MLX with 4-bit quantization, group_size 64, no speculative decoding or batching, at a 4k prompt (4138 actual tokens) with 128 output tokens. The figure is one observation, not a repeated-run mean, from a single timed generation.

User reports Llama 3.1 8B at 72.9 t/s generation and 566.4 t/s prompt processing on a single Apple M2 Max with 64 GB unified memory. Setup is MLX via a direct python -m mlx_lm benchmark, 4-bit quantized, batch size 1, with a requested 512-token prompt and 128-token generation cap. The figures are three-trial means after discarding Trial 1; peak memory was 5.116 in engine output units, and KV cache precision and prefill chunk size are unreported.

User reports Llama 3.1 8B at 101.1 t/s generation and 2758.3 t/s prompt processing on an M5 Max with 48GB unified memory. Setup is llama.cpp build 11146 with Metal, Q4_K_M weights, n_gpu_layers=99 and flash attention enabled. The figures are separate llama-bench microtests, tg128 and pp512, not one 512-input/128-output request; context length is unspecified and KV cache precision was not captured.

User reports Llama 3.1 8B at 115.4 t/s generation and 3225.7 t/s prompt processing on an M5 Max with 48GB unified RAM. Setup is MLX with 4-bit weights and unquantized KV cache, batch size 1, one model per process. The headline uses pp512 and tg128 from a five-trial mean, not a best-of sweep; the source also records pp128=1932.3, pp256=2487.89 and tg256=115.52 t/s.

User reports Llama 3.1 8B at 21 t/s generation and 229.2 t/s prompt processing on an M4 16GB Mac mini. Setup is llama.cpp 0.4.0 with Q4_K_M and Metal, all layers on GPU; context, KV precision and Flash Attention are unknown. The figures come from separate llama-bench tests, pp512 at 229.23 ±0.08 t/s and tg128 at 20.95 ±0.02 t/s over three runs, not a combined 512-input/128-output completion, with 10.29 GiB RAM already in use.

EVR-1 custom compression (~3-bit weights) (GGUF)

Reported by the source; GPU count, offloading and concurrent requests can change these figures. Prompt-processing speed is input throughput, not time to first token. Check the full setup before comparing.

User reports Llama 3.1 8B at 8.2 t/s generation and 9.1 t/s prompt processing on an M4 16GB Mac mini. Setup is Evrmind's custom Metal binary with EVR-1 compression at roughly 3 bits per weight and full GPU offload. The figures come from separate pp512 and tg128 phase tests, not a paired 512-input/128-output run; the source table lists 9.11 and 8.16 t/s.

generation:

quant:

4bit

Reported by the source; GPU count, offloading and concurrent requests can change these figures. Prompt-processing speed is shown only when the source reports it; generation speed cannot tell us time to first token. Check the full setup before comparing.

User benchmarks Llama 3.1 8B on a base M4 Mac, comparing MLX and llama.cpp. Best observed decode is MLX at 23.1 t/s on a quiet machine, with llama.cpp at 11.5 t/s; llama.cpp prefill is 118 t/s with flash-attention and 71 t/s without. Setup uses MLX 4-bit and llama.cpp GGUF Q4_K_M, with a 32K KV cache pre-allocated by llama.cpp. The user notes the memory gap between engines is an artifact of that pre-allocation, with a real weight delta of about 0.3 GB. The user reports decode is bandwidth-bound at roughly 18-22 t/s either way, and that the speed winner flips depending on background load. The MLX checkpoint is lighter at 4.50 bpw versus 4.90 bpw for llama.cpp.

User benchmarks Llama 3.1 405B at 2.99 t/s on a single M3 Ultra 512GB node. Setup is MLX with Q4 quantisation at 1K context, single node. This is part of a 200+ configuration campaign across 5 models and 9 topologies on a 5-node M3 Ultra cluster; the report also covers Qwen 2.5 32B, Mixtral 8x7B, DeepSeek V3.2 and Kimi K2.5, with TP and PP scaling results.

F16 (GGUF)

Reported by the source; GPU count, offloading and concurrent requests can change these figures. Prompt-processing speed is input throughput, not time to first token. Check the full setup before comparing.

User reports Llama 3.1 70B F16 at 2.27 t/s generation and 39.10 t/s prompt processing on a dual AMD Epyc Turin CPU system. Setup is llama.cpp with GGUF F16 weights, 32 threads, --numa distribute, CPU only. User found that token generation is bottlenecked by remote NUMA memory accesses caused by llamafile_sgemm() during prompt processing; running generation-only first raises it to 4.30 t/s. A similar effect is shown for phi-4 14B F16, where disabling GGML_USE_LLAMAFILE raises generation from 10.59 to 17.26 t/s but drops prompt processing from 187.03 to 85.66 t/s.

Q8_K_R8 (GGUF)

Reported by the source; GPU count, offloading and concurrent requests can change these figures. Prompt-processing speed is input throughput, not time to first token. Check the full setup before comparing.

User benchmarks LLaMA-3.1-8B on CPU with ik_llama.cpp and llama.cpp, reporting prompt processing of 370.11 t/s with Q8_K_R8 on a Ryzen 7950X. Setup uses llama-bench for PP-512 and TG-128, with -rtr 1 for ik_llama.cpp; AVX2/Zen4 on Ryzen-7950X and ARM on M2-Max. User reports ik_llama.cpp is up to 7x faster for prompt processing and notes the slowest ik_llama.cpp quant beats the fastest llama.cpp quant on Ryzen-7950X.

User reports LLaMA 3.1 8B at 11.6 tok/s sustained (11.9 peak) on a Motorola Moto G Stylus 5G with Snapdragon 6 Gen 1 and 8GB RAM, running CPU-only. Setup is a custom pure Rust runtime with 1.58-bit ternary quantization, speculative decoding, and mmap; model size is about 2.05 GB with 2.10 GB active RAM. Single-token decode without speculation is 4.2 tok/s. Qwen 2.5 1.5B reaches 20.3 tok/s at about 480 MB. WikiText-2 perplexity is 6.45 for the 8B and 9.15 for the 1.5B.

User reports Llama 405B Q4_K_M at 1.2 t/s two years ago, and contrasts it with current speeds of 30-100 t/s for newer models including Kimi K2.6, DeepSeek V4 Flash, MiniMax 2.7, Step 3.5 Flash and Qwen3.5-397B. User also mentions running Qwen3.6-36B at 50 t/s for a few hundred dollars.
