✅100+% more PCIe lanes (48 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics for 12th Gen, while Ryzen 7 5800U needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 7 5800U across 50 shared CPU benchmark tests.
❌Lower PassMark (18,064 vs 18,067).
❌Smaller total L3 cache (12 MB vs 16 MB).
❌266.7% higher power demand at 55W vs 15W.

Ryzen 7 5800U

2021

Why buy it

✅Better for gaming: +5.9% higher average FPS across 50 shared CPU benchmark tests.
✅+33.3% larger total L3 cache (16 MB vs 12 MB).
✅Draws 15W instead of 55W, a 40W reduction.

Trade-offs

❌Older platform position on FP6 with DDR4, while Core i5-12450HX moves to FCBGA1964 and DDR5.
❌No integrated graphics, while Core i5-12450HX can still boot and troubleshoot without a discrete GPU.
