How we got this verdict
16 - 1 = 15GB usable VRAM (the driver and OS reserve roughly 1 GB).
12B lands on Q4_0 here, so grab the official QAT (quantization-aware training) checkpoint instead of a generic Q4_0 quant. Google shipped a full-quality QAT build for 12B at essentially the same ~7.2GB download size, with noticeably better output quality than a naive 4-bit quant. See the QAT guide for exact file names.
Switching to the RTX 4070 Ti SUPER (16GB VRAM) doesn't change the top recommendation — 12B is still the best fit, just with more headroom.
The fastest lever on a fixed budget isn't more VRAM on the same card — it's switching cards. Compare this tier against neighboring cards below, or check the full checker for any GPU model.
Real-world notes for this configuration
The RTX 4060 Ti was sold in two VRAM configurations on the identical GPU core — an 8GB version and a 16GB version, both on the same 128-bit memory bus. This page uses the 16GB variant; the bus doesn't widen with the extra capacity, so the bandwidth-per-GB story is different here than with most VRAM-tier upgrades on other cards.
- ⚠Confirm you have the 16GB variant specifically — the 8GB and 16GB 4060 Ti cards look nearly identical externally and share the same core, differing only in VRAM chip count.
- ⚠The bus stays 128-bit regardless of which VRAM variant you have — more capacity here doesn't come with more bandwidth, unlike most other VRAM-tier jumps in this lineup.

FAQ
Can a RTX 4060 Ti (16GB VRAM) run the 31B flagship model?
No — the 31B model needs at least 17.4GB usable memory even at Q4_0, and this configuration only has 15GB usable. Gemma 4 12B is the largest model that fits here.
What's the best Gemma 4 model for a RTX 4060 Ti (16GB VRAM)?
Gemma 4 12B at Q4_0 (4-bit) (~6.7GB) is the best fit — it's the largest model that runs comfortably within the 15GB of usable memory here.
What if I have more or less memory than 16GB VRAM?
With more (e.g. RTX 4070 Ti SUPER), you can run larger models or the same model more comfortably — see the RTX 4070 Ti SUPER page. With less (e.g. RTX 4070), the best-fitting model gets smaller or tighter — see the RTX 4070 page.
Does the RTX 4060 Ti 16GB have a wider memory bus than the 8GB version?
No — both variants use the same 128-bit bus and the same GPU core; only the VRAM chip capacity differs. The 16GB version's extra headroom doesn't come with extra bandwidth.
How do I confirm I have the 16GB 4060 Ti and not the 8GB one?
Check the box, retailer listing, or run nvidia-smi — the two variants look nearly identical, and the difference matters a lot for local AI capacity even though the core GPU is the same.
