The RTX 5060 Ti 16GB launched in May 2026 at $429 MSRP, and it immediately became the most cost-effective GPU for local LLM inference that a developer can buy today. Sixteen gigabytes of GDDR7 at 448 GB/s bandwidth puts it ahead of the RTX 3090 (24 GB but only 936 GB/s across PCIe 4.0 → often bottlenecked) in practical coding assistant throughput — and well ahead of the 8 GB and 12 GB cards that can't hold a useful code model without aggressive quantization.
This article answers one specific question: if you're a developer running Cursor, Cline, or Continue.dev with a local Ollama backend on an RTX 5060 Ti, which model should you actually use?
The benchmarks below were run live on this machine today. No synthetic estimates, no borrowed numbers.
Why the RTX 5060 Ti Is the Relevant GPU for This Question in 2026
Before the 5060 Ti, the local LLM coding stack hit a wall at the $300–$500 price point. The RTX 4060 Ti 16GB (the previous generation equivalent) was limited to 288 GB/s bandwidth on GDDR6. The RTX 5060 Ti's 448 GB/s GDDR7 bus represents a 56% bandwidth jump, and bandwidth is the dominant bottleneck for autoregressive token generation — especially on quantized models where GPU compute is underutilized.
Concretely, more bandwidth means more tokens per second at the same VRAM level. For coding assistance, where you're generating completions in real time while you type, latency below 50 tok/s starts to feel slow. Below 30 tok/s, you'll wait on the model instead of the model waiting on you.
At $429 MSRP on Amazon, the RTX 5060 Ti sits between the "too slow" 8 GB cards and the "overkill for a workstation" 4090/5090 tier. If you're building a local coding assistant setup on a budget, this is the 2026 answer.

Test Setup
All benchmarks were run on the same machine, same day:
- GPU: NVIDIA GeForce RTX 5060 Ti 16GB GDDR7 (15.9 GB usable VRAM)
- Bandwidth: 448 GB/s
- Runtime: Ollama 0.23.2
- Driver: NVIDIA 596.36
- OS: Windows 11
Test prompt (identical for all three models): "Explain what is artificial intelligence in one paragraph."
This is a single-shot generation test — cold load (model not preloaded in VRAM) and sustained throughput measured from first token.
The Three Models Tested
Llama2 13B — General Baseline
Meta's Llama 2 13B is the benchmark control in this comparison. It's a general-purpose model, not code-specialized. As of mid-2026, it remains in use primarily for:
- Teams that started with it and have it baked into existing toolchains
- Developers who need general chat + code in one model
- Compatibility with older Ollama-based tools that pin specific model names
The Q4_K_M quantization gets it under the 5060 Ti's 16 GB VRAM ceiling. At this quantization level, 13B models typically land around 11–12 GB — which they did.
Mistral 7B — Quality/Speed Balance
Mistral 7B was released in September 2023 and remains one of the strongest 7B-class models by benchmark. It punches above its parameter count on reasoning tasks and has reasonable coding capability despite not being code-specialized. At Q4_K_M, it runs comfortably on the 5060 Ti with 5–6 GB VRAM, leaving room to run other applications concurrently.
Mistral 7B is the practical pick for developers who want a model that handles both coding questions and general development discussion (architecture questions, documentation, debugging narratives) in one session.
DeepSeek-Coder 6.7B — Code-Specialized
DeepSeek-Coder was purpose-trained on code. DeepSeek's training corpus for this model is reported to include 87% code and 13% natural language — the inverse ratio of a general-purpose model. It supports 338 programming languages and was trained with a 16K context window by default.
The 6.7B parameter count is slightly smaller than Mistral 7B, which contributes to its speed advantage. More important: code-specific training means it produces tighter completions, fewer hallucinated APIs, and better multi-file context handling than a general model of comparable size. For a developer using this as a coding assistant (not a chatbot), this distinction matters more than the raw benchmark speed difference.
Benchmark Results
| Model | Quantization | Tokens/sec | VRAM Used | Cold Load |
|---|---|---|---|---|
| Llama2 13B | Q4_K_M | 53.44 tok/s | 11.3 GB | 9.5s |
| Mistral 7B | Q4_K_M | 90.17 tok/s | 5.9 GB | 2.4s |
| DeepSeek-Coder 6.7B | Q4_K_M | 101.44 tok/s | 11.6 GB | 1.7s |
All three models are fast enough for interactive use on the RTX 5060 Ti. The floor for comfortable completion generation in a coding assistant is roughly 40–50 tok/s — everything here clears it. But there are meaningful differences:
DeepSeek-Coder 6.7B is the fastest by a significant margin — 12.5% faster than Mistral 7B and 90% faster than Llama2 13B. At 101 tok/s, completions appear nearly instantaneously. A 200-token function explanation takes under 2 seconds.
The 1.7-second cold load is practically negligible. Mistral 7B at 2.4 seconds is close. Llama2 13B at 9.5 seconds is the one that will make you wait when you first fire up Ollama.
The VRAM surprise: DeepSeek-Coder 6.7B uses 11.6 GB despite having fewer parameters than Llama2 13B (which uses 11.3 GB). The reason is its default 16K context window. The KV cache for a 16K context occupies significantly more VRAM than the model weights themselves at this scale. See the VRAM management section below for how to fix this.

Code Quality: Why Tok/s Isn't the Whole Story
Speed is necessary but not sufficient. A model that generates wrong code at 100 tok/s is worse than a model that generates correct code at 70 tok/s.
DeepSeek-Coder 6.7B's code-specific training shows in practical use:
API hallucination rate is lower. General models like Llama2 will generate plausible-looking but nonexistent function signatures. DeepSeek-Coder's training corpus is overwhelmingly code — it's seen the actual APIs.
Multi-file context handling is better. When you feed it a 500-line component plus a types file, it reasons about the relationship between them. General models at this parameter size often treat each chunk independently.
Docstring and test generation is tighter. Ask DeepSeek-Coder to write a pytest suite for a function and it writes tests that reflect the actual parameter types. Llama2 13B often writes structurally valid but semantically wrong tests.
Language-specific patterns. TypeScript generics, Rust borrow checker idioms, Python type hints — DeepSeek-Coder handles these more consistently because they appear heavily in its training data.
Mistral 7B occupies a middle ground. It's strong on reasoning and can handle "explain why this function is O(n²)" better than you'd expect from a 7B model, but it wasn't trained for code-first completions.
VRAM Note: DeepSeek-Coder's Context Window Default
DeepSeek-Coder 6.7B defaults to a 16K context window. This explains why it uses 11.6 GB VRAM despite smaller parameter count than Llama2 13B.
For most coding assistant workflows — single-file completions, function explanations, short code revi
