TPU has some great data for the discussion here:
We review NVIDIA's GeForce RTX 5060 Ti 8 GB, the card that NVIDIA doesn't want tested. Especially in VRAM-heavy titles the performance drops, but in many cases it's slightly faster than the more expensive 16 GB version, thanks to improved power efficiency.

The Gainward 5060Ti 8GB card they tested is interesting as it isn't overclocked, and comes with reference clocks and the reference 180W TDP limit and can't be changed. I guess not having to have the second set of GDDR7 modules eating power gives some significant extra TDP headroom for the boost algorithm. At 1080p the 8GB card is generally a wee bit faster, but in the VRAM-constrained situations where it loses, it loses
big, and those losses start to pile up as the resolution increases, as you'd expect.
It's also
super strange that the 4060Ti
8GB card beats the 5060Ti
8GB card in some of those same VRAM-hungry titles. Maybe Blackwell's memory management is significantly different than Ada's? Or certain Blackwell features 'reserve' a chunk of VRAM for internal use, like the hardware flip metering? Very odd. I'm willing to chalk this up to a bug for now, as a lot of the data makes no sense, like the 5060Ti winning at 1080p, losing hard at 1440p, but winning again at 4k, in the exact same title, with the exact same amount of VRAM.
The 5060Ti has more of
everything compared to the 4060Ti: more cuda cores, more TMUs, more tensor cores, more RT cores, the same 48 ROPs, slightly higher clocks, PCIE 5.0 x8 vs PCIE 4.0 x8 which should help in VRAM constrained situations, the same 32MB of L2 cache, and most importantly, a whole truckload more memory bandwidth (~56% more!)
A thing to note for all the charts on the page though, is that these are all tested at native resolution and
without RT, so the absolute
best case scenario for a card that's heavily VRAM constrained.
Lots of common options that people would use with such a card will eat into the VRAM budget further, like:
- Enabling RT (hello, BVH storage costs)
- Enabling DLSS (which you probably realistically would always want to in a card of this class)
- Enabling DLSS FG (which also would probably be leaned on extremely heavily in a card of this class)
- Multitasking / streaming / video encoding / decoding while gaming
