RTX 4060 Ti 16 GB
Budget 16 GB option; 70B Q4 fits with tight context.
RTX 4070 Ti Super
16 GB Ada midrange; balanced consumer pick.
Both have 16 GB VRAM — the threshold for fitting 70B Q4 with tight context. The 4060 Ti's 288 GB/s bandwidth is the limiting factor; the 4070 Ti Super at 672 GB/s is roughly 2.3x faster on memory-bound decode.
Price-wise, the 4060 Ti 16 GB sits at $450-550; the 4070 Ti Super at $800-1,000. For 13B-32B models, the 4060 Ti is fine. For 70B Q4 daily use, the 4070 Ti Super's bandwidth advantage shows up as visibly faster tok/s.
Buyer reality: the 4060 Ti 16 GB is the cheapest path to 70B Q4 on a single card. The 4070 Ti Super is the cheapest path to comfortable 70B Q4.

Who should AVOID each option
Avoid the RTX 4060 Ti 16 GB
- If 70B is your daily target — bandwidth bottleneck is real
- If you're chasing maximum single-card tok/s
Avoid the RTX 4070 Ti Super
- If 13B-32B is your target — bandwidth advantage doesn't help much
- If price-per-card matters more than per-card speed
Workload fit
RTX 4060 Ti 16 GB fits
- 13B-32B daily use
- Budget multi-card rig
- Learning local AI
RTX 4070 Ti Super fits
- 70B Q4 single-card
- Single-user balance
- Mid-tier consumer

Editorial verdict
If your daily target is 13B-32B models, the 4060 Ti 16 GB at $450-550 is the right value pick. The 16 GB ceiling fits everything in that range comfortably; bandwidth isn't a constraint for smaller models.
If 70B Q4 is the goal, pay up for the 4070 Ti Super. The 4060 Ti's 288 GB/s makes 70B feel sluggish (6-9 tok/s); the 4070 Ti Super's 672 GB/s keeps it usable (14-20 tok/s).
Multi-card 4060 Ti 16 GB rigs are interesting at this price. Two cards = 32 GB combined for ~$1,000. The bandwidth ceiling persists per-card, but for 70B Q4 on a tight budget it's a real option.
HonestyWhy benchmark numbers on this page might not reflect your real experience
- tok/s is not user experience. Humans read at ~10-15 tok/s — anything above that is buffer time, not perceived speed.
- Context length changes everything. A 70B Q4 model at 1024 tokens generates ~25 tok/s; the same model at 32K context drops to ~8-12 tok/s as KV cache fills.
- Quantization changes the conclusion. Q4_K_M vs Q5_K_M vs Q8 produce different speed AND different quality. A benchmark at one quant doesn't translate to another.
- Thermal throttling changes long sessions. The first 15 minutes of a benchmark see boost-clock peak; the next 4 hours see steady-state, which is 5-15% slower depending on case airflow.
- Driver and runtime versions silently shift winners. A 2024 benchmark on PyTorch 2.4 + CUDA 12.4 doesn't reflect 2026 reality on PyTorch 2.6 + CUDA 12.6. Discount benchmarks older than 6 months.
- Vendor and YouTuber benchmarks are cherry-picked. The standard 'Llama 3.1 70B Q4 at 1024 tokens' chart shows peak decode on a tiny prompt — exactly the conditions least representative of daily use.
- A 25-30% throughput gap between two cards rarely translates to a 25-30% experience gap. Both cards are fast enough; the differentiator is usually VRAM ceiling, not raw decode speed.
