❌Lower PassMark (9,167 vs 9,202).
❌Less compelling for workstation-style loads than Xeon E3-1275 v6, which brings 4 cores / 8 threads.

Xeon E3-1275 v6

2017

Why buy it

✅Better for gaming: +16.6% higher average FPS across 50 shared CPU benchmark tests.
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

❌Launch MSRP is still $499 MSRP, while Pentium Gold 8505 mostly shows up through inconsistent older-market listings.
❌32.7% higher power demand at 73W vs 55W.
❌Older platform position on LGA1151 with DDR4, while Pentium Gold 8505 moves to FCBGA1744 and DDR5.
❌No integrated graphics, while Pentium Gold 8505 can still boot and troubleshoot without a discrete GPU.
