Will the Ryzen 7 8700G bottleneck the RTX 5070 Ti?

Yes, at 1440p the Ryzen 7 8700G is estimated to limit the RTX 5070 Ti by about 12%. The effect is larger at 1080p and smaller at 4K.

What power supply do I need for a Ryzen 7 8700G and RTX 5070 Ti?

Estimated system load is about 465 W. A quality 650 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 19% (mild CPU bottleneck). 1440p: CPU-limited 12% (mild CPU bottleneck). 4K: GPU-limited 10% (balanced).

Ryzen 7 8700G + RTX 5070 Ti: bottleneck check

12%

CPU-limited at 1440p. Mild CPU bottleneck.

CPU GPU

The Ryzen 7 8700G cannot feed the RTX 5070 Ti fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	19%	mild CPU bottleneck
1440p	CPU	12%	mild CPU bottleneck
4K	GPU	10%	balanced

This is the classic pattern: at 1080p the Ryzen 7 8700G is the limit (19%), while at 4K the RTX 5070 Ti takes over (10% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply

CPU 65 W + GPU 300 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 465 W. We recommend a 650 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
