Quick Answer
The RTX 4060 Ti 16GB is identical in performance to the 8GB model in games that use under 8GB VRAM. In titles exceeding 8GB at 1440p (Hogwarts Legacy, The Last of Us), the 16GB model avoids stutters. The 16GB version costs $80-100 AUD more.
Both cards have identical cores, clocks, and TDP (160-165W). The only difference is 8GB vs 16GB of GDDR6 memory. They perform identically in every game that fits within 8GB of VRAM.
At 1080p, virtually no current game exceeds 8GB VRAM. At 1440p, most titles use 6-8GB on High settings. In these scenarios, the 8GB and 16GB models produce identical frame rates.
A growing number of 2026 titles exceed 8GB at 1440p Ultra:
For roughly the same price as the RTX 4060 Ti 16GB, the RX 7700 XT offers 12GB VRAM and faster rasterization. It is a compelling alternative if DLSS 3 is not a priority.
Our Verdict
If you play at 1440p and want longevity, spend the extra $90 for 16GB. If you play at 1080p, the 8GB is sufficient. For the best value, consider the RX 7700 XT at similar pricing with 12GB and faster rasterization.
The best 1440p GPU under $800 AUD is the RX 7800 XT at around $620 AUD. It delivers outstanding 1440p performance with 16GB VRAM for future-proofing. The RTX 4070 at $750 AUD is the alternative if you value DLSS 3 and ray tracing.
The best GPU for the i5-13400F under $600 AUD is the RTX 4060 Ti 8GB at around $500-550 AUD. It delivers excellent 1080p and capable 1440p performance without bottlenecking on this CPU. The RX 7700 XT is a strong alternative at similar pricing.
The RTX 4060 is 10-15% faster than the RX 7600 in rasterization and significantly better in ray tracing. It also has DLSS 3 Frame Generation. However, the RX 7600 costs $50 AUD less. The RTX 4060 is the better GPU; the RX 7600 is the better deal.
