Pentium Gold 8505

2022

Why buy it

✅Draws 55W instead of 85W, a 30W reduction.
✅Newer platform on FCBGA1744 with DDR5 support instead of LGA3647 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics, while Xeon Silver 4108 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon Silver 4108 across 50 shared CPU benchmark tests.
❌Lower PassMark (9,167 vs 9,177).
❌Smaller total L3 cache (8 MB vs 11 MB).
❌Less compelling for workstation-style loads than Xeon Silver 4108, which brings 8 cores / 16 threads.

Xeon Silver 4108

2017

Why buy it

✅Better for gaming: +15.2% higher average FPS across 50 shared CPU benchmark tests.
✅+37.5% larger total L3 cache (11 MB vs 8 MB).
✅Better for workstations and heavier parallel workloads: 8 cores / 16 threads.

Trade-offs

❌Launch MSRP is still $417 MSRP, while Pentium Gold 8505 mostly shows up through inconsistent older-market listings.
❌54.5% higher power demand at 85W vs 55W.
❌Older platform position on LGA3647 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.

Quick Answers

So, is Xeon Silver 4108 better than Pentium Gold 8505?

Not really, because they are built for different jobs. Xeon Silver 4108 makes more sense for workstation-style multi-core throughput, while Pentium Gold 8505 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon Silver 4108 is the better pick. According to our tests, it delivers 15.2% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon Silver 4108 is the stronger fit. You are getting 0.1% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 37.5% larger total L3 cache (11 MB vs 8 MB).

Which one is the smarter buy today, not just the cheaper CPU?

Xeon Silver 4108 is the better buy right now. Xeon Silver 4108 comes in at an unclear MSRP at $417 MSRP versus unclear MSRP, and it still gives you a 15.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (22.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?

Pentium Gold 8505 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017) and a healthier platform with FCBGA1744 and DDR5 instead of LGA3647. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
