Indeed, but the race between TSMC and Intel to scale up 200+ MTr/mm^2 processes should benefit us all. Both AMD and Apple have good micro-architectures to produce at TSMC, and Intel is mostly behind on process, so if we can keep that race going maybe we can still have ~2x performance every ~2 years for a while longer. I'm looking to switch laptops and was surprised to find out that after 5 years and as many generations I can be right on track for that performance growth.
- christkv 5y agoI would think the chiplet strategy that AMD used is also a benefit compared to Intels more monolithic design when it comes to yields.
- lumost 5y agoI am curious how much of the process delay in Intel came from having chip design and manufacturing under one umbrella. If AMD wanted the latest process they had to deal with the limits TSMC said they could achieve. Intel's chip team could simply push back on their manufacturing team to improve reliability via leadership. If Intel had gone with chiplets would 10nm have been delayed?
- chmod775 5y ago> maybe we can still have ~2x performance every ~2 years for a while longer At no point in the past 20 years did we even come close to that. You're probably thinking of Moore's Law, which refers to transistor count, not performance.
- mlyle 5y agoCPUMark is a flawed benchmark, but.. in 2004 the average score was 385 on Desktop. In 2012, it was 4626. So-- that's 12x in 8 years, vs. 16x from doubling every 2 years. I'd say we used to come close. For the past 5 years, it's been doubling about every 3 years.
- pedrocr 5y agoI'm thinking of actual benchmarks. Here's the one I've been looking at: https://www.cpubenchmark.net/compare/AMD-Ryzen-7-PRO-4750U-vs-AMD-Ryzen-7-PRO-5850U-vs-Intel-i5-6200U-vs-Intel-i7-6600U-vs-Intel-i7-1185G7/3740vs4198vs2556vs2608vs3793 https://www.cpubenchmark.net/compare/AMD-Ryzen-7-PRO-4750U-v... The top CPU choice for my current Lenovo T460s was the i7-6600U. Exactly 5 laptop generations later the top CPU choice for the T14sG2 is the Ryzen 7 5850U. The ratio of performance between those two is 5.82. That's 42% per year or almost exactly 2x every 2 years on the same form factor and TDP. Last year's 4750U was at 4.4x after 4 years. Intel has only been able to do 1.6x every 2 years in the same comparison. Their single core performance is comparable but they've only been able to deliver 4 cores versus AMD's 8.
