What LLMs can an RTX 5070 Ti 16GB run?

An RTX 5070 Ti 16GB runs 21 of the 69 open models tracked here at Q4_K_M with 8K context; the largest is gpt-oss-20b (20.9B parameters, 14.8 GB at MXFP4). It reads memory at 896 GB/s. 13 more fit at a lower precision. Each fit leaves at least 0.5 GB free on the RTX 5070 Ti 16GB (why a card does not give a model all its memory).

Best models for RTX 5070 Ti 16GB with room for long context

The biggest models that still fit at Q4_K_M with 32,768 tokens of context (or their whole window, if shorter), the memory left over, the longest context the card takes at that precision and the writing speed with that context in the cache, from 896 GB/s of bandwidth. gpt-oss-20b is at MXFP4, as published.

How fast the RTX 5070 Ti 16GB writes as the context fills

Tokens per second at Q4_K_M (gpt-oss-20b at MXFP4) for the biggest models that fit with 32K tokens, with 8K and 32K tokens in the cache and at the longest context the card holds, and at Q8_0 with 8K where that fits. Each token reads the active weights and the whole cache once, so the speed follows the 896 GB/s of bandwidth and falls as the cache grows. The ceiling is that bandwidth divided by the bytes read per token, which no runtime reaches; the reply time is for 1,000 new tokens with 32K (or the longest context) in the cache, prompt processing aside. With the same memory, RTX 4060 Ti 16GB, 288 GB/s, writes 66% slower on average; RTX 5060 Ti 16GB, 448 GB/s, writes 48% slower on average; RX 9070 XT 16GB, 644 GB/s, writes 26% slower on average; RTX 4070 Ti Super 16GB, 672 GB/s, writes 23% slower on average; RTX 4080 Super 16GB, 736 GB/s, writes 17% slower on average; RTX 5080 16GB, 960 GB/s, writes 6% faster on average.

RTX 5070 Ti 16GB against the other 16 GB cards

The same models fit on every card with 16 GB, so speed is what separates them. By bandwidth the RTX 5070 Ti 16GB ranks 2 of 7 at 896 GB/s. Over the 12 biggest models that fit at Q4_K_M with 8K context, the RTX 4060 Ti 16GB (288 GB/s) writes 66% slower, the RTX 5060 Ti 16GB (448 GB/s) writes 48% slower, the RX 9070 XT 16GB (644 GB/s) writes 26% slower, the RTX 4070 Ti Super 16GB (672 GB/s) writes 23% slower, the RTX 4080 Super 16GB (736 GB/s) writes 17% slower and the RTX 5080 16GB (960 GB/s) writes 6% faster than the RTX 5070 Ti 16GB. Each cell below is the other card's tokens per second minus this one's, midpoints of the estimated ranges.

In system RAM counts the offloaded experts plus the input embedding (token_embd), which llama.cpp keeps in RAM in any case.

How these numbers are worked out

Memory is the weights at each precision plus the KV cache for 8,192 tokens in FP16 and runtime overhead (0.5 GB plus 10%), computed from each model's files on Hugging Face with the LLM VRAM Calculator. Speed is estimated from memory bandwidth and the parameters read per token with the LLM Speed Calculator. Both tools take any other model from Hugging Face.
