Missing the most important metric: processing power per watt.
I have some server CPUs laying around that can also beat Apple CPUs. But putting them in a compact, densely packed, sealed box (aka a phone) would result in a fireball and almost no battery life.
- cyp0633 2mo agosome chinese youtubers have posted their test results, seems pretty good, but the devices have been provided to them in advance fwiw
- StilesCrisis 2mo agoI'm sure it benchmarks well, but does it actually have good battery life?
- frollogaston 2mo agoEven aside from battery life, high TDP means thermal throttling under sustained load. Which most of these benchmarks don't really test, or if they did, the ambient temperature affects the results.
- sorz 2mo agoThey do test continuous (1-hour) gaming performance in controlled environment regularly. Thermal throttling can be easily spotted on the frame rate vs time graph.

- StilesCrisis 2mo agoThe goalposts have been at "performance-per-watt" for a very, very long time. That was why Apple pivoted from PowerPC to Intel, believe it or not. PowerPC laptops couldn't match the battery life of Intel, so Apple pivoted. How times change!
- KerrAvon 2mo agotop comment right now on this very page: "But actual results inside phone with smartphone cooling and wattage requirement became close to 3300"
- well_ackshually 2mo agoNo lmao, top comment is saying MediaTek's variant of an ARM C1 Ultra dropped to 3300, attempting to link it to this CPU through vibes and magic
- strictnein 2mo agoI mean, they're in a thread on my comment whose point is "let's see power per watt". The goalposts started there. A comment responded to me by saying some Chinese youtubers found it to be good. The person responded saying "but what about battery life" which was the original topic. The person you're responding to also has never said anything about any other metric.
- mort96 2mo agoDid their test results include power draw?
- throwa356262 2mo agoYes, and it looked pretty good for an engineering sample. See this video from chineese youtubeer geerkerwan: https://m.youtube.com/watch?v=BCCJuOopLK8 https://m.youtube.com/watch?v=BCCJuOopLK8
- mort96 2mo agoOh, so we're at the "good for an engineering sample" stage not "competitive with Apple" stage
- throwa356262 2mo agoNot sure what you mean, but production silicon will be used in their phones next month.
- mort96 2mo agoI mean that we don't have numbers for how this competes with Apple
- zamadatix 2mo ago> I have some server CPUs laying around that can also beat Apple CPUs In multicore, sure. In most single threaded workloads as well? That'd be interesting enough on its own, regardless of wattage (though that'd make it even more interesting), as my A19 device gives my overclocked 9800X3D a run for its money (and some losses) in single threaded workloads. Considering that's the only thing the 9800X3D is really targeting, it's impressive beyond just whether or not it does so with less power.
- kccqzy 2mo agoNo I don’t think you can find a single CPU that can beat Apple CPUs in a single-threaded workload.
- bigyabai 2mo agoUnless you're benchmarking single-threaded SIMD: https://lemire.me/blog/2020/12/13/arm-macbook-vs-intel-macbook-a-simd-benchmark/ https://lemire.me/blog/2020/12/13/arm-macbook-vs-intel-macbo...
- mrheosuper 2mo agoit's 6 Year old blog, apple has improved a lot with ST, i argue that it's even more than Intel and AMD in the same timeframe.
- bigyabai 2mo agoBe that as it may, Apple has not added any real AVX-equivalent SIMD block. AMD and Intel's chips will generally lap them in SIMD benchmarks.
- throwa356262 2mo agoO3 is supposed to draw 25% less than O1, which according to reviews of their tablets did not throttle. Their next Fold phone (TBA September) will use O3. I guess we will find out very soon.
