Every quant, against this card

Weight bytes are the size of the real published file wherever one exists — 6 of these6 rows are measured from bartowski/DeepSeek-R1-Distill-Llama-8B-GGUF, the rest computed from the parameter count. Max context is what the KV cache can grow to in whatever memory the weights leave behind, capped at the 128k tokens this model was trained to address.

What the context actually costs

The KV cache is 2 · layers · kv_heads · head_dim bytes per token per element — 2 · 32 · 8 · 128 · 2 B = 128.0 KiB. It depends on the key/value head count, not the attention-head count and not the parameter count. This model shares 8 KV heads across 32 query heads, which divides the cache by 4 against multi-head attention.

Context	KV cache (FP16)	KV cache (8-bit)	Plus Q4_K_M weights
4,096	512 MiB	256 MiB	5.1 GiB
8,192	1.0 GiB	512 MiB	5.6 GiB
32,768	4.0 GiB	2.0 GiB	8.6 GiB
131,072	16.0 GiB	8.0 GiB	20.6 GiB

The speed ceiling, and where it comes from

Generating one token reads every active weight from memory once. At Q8_0 that is 8.0 GiB, plus a pass over the KV cache. A GeForce RTX 4060 Ti 16GB moves 288 GB/s (128-bit × 18 Gbps), so the arithmetic ceiling is 30 tok/s. Treat it as a bound, not an estimate: attention overhead, kernel launches and imperfect memory access keep real runtimes at roughly 60–80% of it, and nothing pushes past it.

Where these numbers come from

The model

Parameters: 8,030,261,248
Layers: 32
Attention / KV heads: 32 / 8
Head dimension: 128
Trained context: 131,072
Checkpoint as published: 15.0 GiB

Read from deepseek-ai/DeepSeek-R1-Distill-Llama-8B. The parameter count is the Hub's own total over the tensor shapes, not a figure taken from the model's name.

The accelerator

Memory: 16 GB GDDR6
Bandwidth: 288 GB/s
Bus: 128-bit × 18 Gbps
Assumed usable: 92% → 14.7 GiB

Capacity and bandwidth from the vendor's specification. The bandwidth figure is checked against the bus width and data rate it derives from. The usable fraction is an assumption, not a spec: a driver context, compute workspace and any attached display come out of the same pool before a weight is loaded.

Questions this pairing answers

How much VRAM does DeepSeek-R1-Distill-Llama 8B need?

15.0 GiB for the weights at FP16 — 8B parameters at two bytes each — and 4.6 GiB at Q4_K_M. The KV cache is on top of that and is not a fixed number: this model spends 128.0 KiB per token of context, so 8,192 tokens costs a further 1.0 GiB. A GeForce RTX 4060 Ti 16GB makes 14.7 GiB of its 16 GB available on the assumption below.

Can a GeForce RTX 4060 Ti 16GB run DeepSeek-R1-Distill-Llama 8B?

Yes, quantized. Q8_0 is the largest that fits, leaving room for 54k tokens of context. That is the weights and the KV cache together, against 14.7 GiB of usable memory.

How fast will DeepSeek-R1-Distill-Llama 8B run on a GeForce RTX 4060 Ti 16GB?

No faster than 30 tokens/second at Q8_0, and in practice below it. Decoding is memory-bound: every token reads all 8.0 GiB of weights plus the cache, and this card moves 288 GB/s. That division is the ceiling — no kernel, runtime or driver beats it, and a real runtime typically reaches 60–80% of it.

Why does the context length change how much memory DeepSeek-R1-Distill-Llama 8B needs?

Because the KV cache holds one key and one value vector per token, per layer, for the whole conversation, and it is allocated separately from the weights. This model has 32 layers and 8 key/value heads of 128 dimensions, shared across 32 query heads — grouped-query attention, which divides the cache by 4. That works out at 128.0 KiB per token. Parameter count tells you nothing about this number.

Method and limits. Weight bytes are the byte size of the real published file wherever one exists, and the model's exact parameter count times the published llama.cpp bits-per-weight where it does not. That distinction is on every row above and it matters at both ends: a sub-1B model's Q4_K_M file runs a third larger than the nominal figure because k-quants keep its embedding tables at higher precision, and an already-4-bit release cannot be quantized upward at all. The KV cache is 2 · layers · kv_heads · head_dim · bytes per token, summed over layers with each sliding-window layer capped at its window. The speed figure is a roofline bound, not a benchmark: bandwidth divided by bytes read per token, which no runtime exceeds and every runtime falls short of. The usable fraction of card memory is an assumption: 92% here, which is what this lane assumes for a dedicated card — the other class assumes 75%, so it is not one number applied to every device. That is the only assumed input on this page; every other figure is computed from the model config and the card's published specification. Nothing on this page is written by a language model.
