Max from Hardware Numb3rs joins Tom to discuss everything AMD & Intel Overclocking! What are the benefits? Do some architectures benefit more from overclocking? What got us into tweaking?

0:00 Opening PSA

3:37 Guest Introduction

9:27 What got us into Overclocking? Would we still recommend overclocking anymore?

20:47 Did you think Zen 1 would be a success?

27:47 Was Coffee Lake good enough?

31:37 How IPC scales with Frequency…or doesn’t!

36:03 Zen 2 vs Coffee Lake @5GHz

41:32 Zen+ vs Zen 2 @5GHz

44:30 The importance of Zen 2 DDR4 + FCLK Overclocking

50:37 Intel’s Mesh Architecture

56:27 What FCLK is required for Zen 2 to dominate at 5GHz?

59:07 Zen 3 & Matisse 2 Expectations

1:05:42 Should we use God-Tier components to benchmark budget products?

1:16:15 Intel’s diminishing of 14nm IPC with Security Updates, & their 10nm Architectures.

1:23:45 Is AMD preparing to get more Monolithic? What will Zen 4 look like?

1:32:56 Future Testing & Horse Riding

2021-12-04 23:04:30 I think the 19% seems huge because it is: 1. Haswell -> skylake was underwhelming in IPC increase (~10% iirc) 2. they skipped cannonlake because it broke af. Getting to 25% is easy, (5% more IPC over Icelake) That seems like an actual real estimate. 1.5 and 1.8 are both 20% IPC increases. Very much theoretical target instead of "We think our design changes can get us to here".

I also don't find 80% increase over skylake to be that impressive. Looking at the timeline. that's only ~7.6% IPC/year provided it launches in 2023. That simply isn't that insane. ARM and Apple have been doing over that a year on average for a while, iirc. AMD is ~9% currently, will be 11-13% with Zen3 if you count it as 2020. Probably about 9% if you count Zen3 as 2021.
