Phenom II X6 1045T

2010

Why buy it

✅Draws 95W instead of 120W, a 25W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 7 7800X3D across 2 shared CPU benchmark tests.
❌Lower PassMark (3,244 vs 34,293).
❌Older platform position on AM3, while Ryzen 7 7800X3D moves to AM5 and DDR5.
❌No integrated graphics, while Ryzen 7 7800X3D can still boot and troubleshoot without a discrete GPU.
