We don't know how linearly that benchmark scales.The design helps push the Renoir APU ahead of the Tiger Lake part by up to 31.8%. Some might argue that the margin is underwhelming when you consider the fact that the Ryzen 7 4800U has double the number of CPU cores as the Core i7-1065G7.
Cache costs money (via more die area) and burns power. The performance benefits it confers tend to be logarithmic, although there are certain to be discontinuities for some workloads.I always wondered why they don't use a "ton" of cache
Thanks for posting. That's indeed interesting.
For the 4700U it was dual channel – it is stated in the benchmark report itself (look again here) under the memory information (channels: 2). If anything it is for the Intel system (look again here) where we don’t have this information – although since it is 16GB it probably was 2x8GB instead of 1x16GB.I do worry about things like that, ambient temperature, unobstructed airflow, and whether both had dual-channel memory configurations (note the Intel laptop has 2x the RAM).
Or on somebody's bed. I'd look for a couple more Ryzen benchmarks, just to be sure there's nothing weird about that sample.I think it is reasonable to assume that these benchmarks were run on a table/desk and not wrapped up in a blanket or something obstructing airflow in different ways.
Should be, but it's not a 100% guarantee. Especially if the Intel chip is the higher-end option. Though, I'd agree that the same chassis has the best chance of being identical.They are in the same chassis so identical in terms of thermal/cooling solutions (ventilation, heatpipes, fan).
My office (an upstairs bedroom) gets up to 85 F, in the summer (well tolerable, if the air is dry and I'm using a fan). In an air conditioned lab, where the Intel machine is likely being tested, it could be as cool as 65 F.As for ambient temperature we can reasonably assume they were both tested in a room with humanly tolerable temperatures.
Thanks for that. Tiger Lake looks to be an exciting launch, then.Besides we have more similar results anyway. There are two more 1165G7 cpus in Acer Swift SF314 laptops (see here, ST:1508, MT: 5811 and here, ST:1451, MT: 5890), performing similarly/slightly better than the result I quote above (ST:1486, MT: 5827). Meanwhile we have one more test of a 4700U in an Acer Swift SF314 laptop (see here (ST:1070, MT: 4723) ) doing similarly to the scores I quoted above (ST: 1068, MT 4637).
