![]() ![]() ![]() Load distribution is also fairly even and follows a similar pattern on each core shown. The ‘multi-core’ tests only attain 100% briefly on all cores, but average well over 50% throughout, and were sufficient to bring the iMac’s fans up to speed. In fact the ‘single core’ tests are distributed across all eight cores, but look as if their total represents something approaching 100% load on a single core, confirmed by the figure given in Activity Monitor’s main window. Being an Intel CPU, the cores on the left with odd numbers are ‘real’, and those with even numbers on the right are virtual cores achieved in Hyper-Threading. In this case, Geekbench ‘single core’ tests were run for the period starting about a third of the way across each panel, then the ‘multi-core’ tests cut in just after half way, and are reflected on all the cores, until they complete and load drops to almost zero. In each of these CPU History windows, time passes from left (oldest) to right (newest) for each of the panels, with red representing system load and green the app load. Here’s what I see in Activity Monitor’s CPU History window for a typical test run. My starting point is running widely used benchmarks in Geekbench 5 on the 8-Core Intel Xeon W processor in my iMac Pro. Is it faster than equivalent processors made by Intel or AMD, and is an M1 Pro faster than the original M1? Over the last year, I’ve been looking at different ways of measuring this for Apple’s M1 chips, and this article and its sequels summarises some of the lessons so far. At 15Watts it's more like 1422 single and 6427 multi threaded (didn't test Linux at 15 Watts) which isn't that impressive when you compare it against the Tiger Lake's 5955 multi threaded score with only half the number of CPU cores: clearly Ryzen is starved for power at 15 Watts.One of the first things you want to know about any new processor or chip with processor cores is its performance. On the mobile 5800U I get 1431 single and 7900 on the 28Watts envelope with Windows while Linux will deliver 14. Actually it even puts it above my 5800X (1696) and 5950X (1690) single Windows scores while Linux will righten the balance with 1794/1784 on the Ryzens.įor the multi-threaded benchmarks my 5950X will deliver 16619 on Linux while the top result on Windows is 15492. My Tiger Lake NUC i7-1165G7 single core results on Linux (1721) seem to imply much faster hardware than on Windows (1568). Generally I observed much higher results with Linux or Android-x86 than Windows on the very same hardware. I have consistently found a relatively high OS bias in Geekbench results, which I actually assume to be mostly a compiler bias given the nature of those benchmarks. Well with a sample of one non-retail system, these results may not be meaningful. Perhaps, usage of faster memory would have given Intel's ADL-P an advantage, but we will need to run our own tests to find out. Furthermore, it is considerably behind Apple's M1-series system-on-chips that have been single-thread performance leaders for about a year now. Quite surprisingly, Intel's Core i7-12700H 'Alder Lake-P' fails to beat the Core i7-11800H 'Tiger Lake-H' as well as AMD's Ryzen 7 5800H 'Cezanne' (Zen 3) in single-threaded workloads. Since overall GB5 results are heavily impacted by cryptography, it makes sense to look at integer and float benchmark results of the new CPUs and compare them to respective numbers obtained on other processors. Because Alder Lake-P officially lacks AVX-512 support, the processor will be slower than chips supporting these instructions in certain workloads. Intel's Core i7-12700H CPU packs six high-(P)erformance Golden Cove cores and eight energy-(E)fficient Gracemont cores, so it should perform considerably better compared to Intel's existing mobile CPUs in multi-threaded workloads. Meanwhile, it looks like both machines are equipped with DDR4-3200 memory, which might have limited their performance in single-threaded workloads. The numbers demonstrated by both machines are really close, so we can assume that the readings are more or less accurate. Alleged Geekbench 5 results obtained on Gigabyte's Aero 5 XE and HP's Omen 17 laptops with Intel's Core i7-12700H inside were added to the benchmark's database on Friday, revealing the performance of the upcoming mobile Alder Lake-P in this popular synthetic benchmark. ![]()
