Ryzen: Strictly technical

I may be wrong: PPT - Package Power Tracking, how close to VRM limit the CPU package power draw is, 100% (maximum) should throttle. TDC - Thermal Design Current, maximum current available in a load condition based on the thermal situation (sustained / avg VRM capacity when hot, 100% is maximum)...

Lenovo released a Cannon Lake laptop

If I already gave links with the score ranges, and scores are all over the place, why pick two results? The 8121u there has much higher memory bandwidth.

A better comparison is the i3 8130u, an 8th Gen KBL-U product. (2.2 / 3.4, 15w) In CB15, it scores 140/338 in an Acer Aspire 3: https://www.notebookcheck.net/Acer-Aspire-3-A315-51-I3-8130U-SSD-FHD-Laptop-Review.302252.0.html If the 8121u scores 139/306, IPC might be up somewhat (139 @ up to...

Apple A12 benchmarks

If AMD gets anything close to GloFo's stated 55% reduction in power and improves their architecture somewhat at 7nm, they will be closer. A Zen 2 SoC could provide around the same performance at "7.5w" package TDP as the A12 does in GB4. Unless I've missed some other information, we also have no...

Apple A12 benchmarks

So much of what I said got completely ignored or only bits and pieces of what I said were analyzed with a very limited perspective to drill the point about single threaded wattage / TDP into the ground, and that wasn't even stated clearly by the other person in the first place, though the...

Apple A12 benchmarks

I see it, but you can't make a direct comparison with these 8th Gen SKUs, the 8650u reaches 300 MHz higher frequency and will consume more power if given the same voltage, due to higher thermals (increased transistor leakage current related to higher temperature). Platform power also matters...

Apple A12 benchmarks

This is part of the reason I said the spread is larger. Most other PC benchmarks are not as sensitive to crypto or memory bandwidth / latency. PCs are often configured with different memory speeds, which have a relatively large influence over the overall score in GB4, smaller than the real-world...

Apple A12 benchmarks

I don't agree. Many reviewers leave GeekBench out of their test suites because of the inconsistency. Maybe laptop reviewers are using it most, but even then, the spread is all over the place across different devices, even if the results look more equal in other benchmarks. Are you assuming the...

Apple A12 benchmarks

It doesn't matter, the chip is not running the maximum turbo frequency under multi-threaded load. Only single thread will be similar, but if intel normally allocates >15w to a single core for the maximum turbo frequency (highly likely) that will be a little lower too. Yes. There are no Linux...

AMD AMA - Starts at 12PM EST on Wednesday May 9

Thank you James for answering our questions. Is Raven Ridge still on GloFo's original 14nm process that Summit Ridge was produced with, or run with some / all of the "12nm" optimizations, or totally different optimizations than the "12nm" process has? I have seen Raven Ridge being referred to...

I am interested in what the power consumption of Apple's SoC's are under loads. I am under the impression that Apple is fine using up all of its available TDP for single threaded performance. The i7 8650U scores really high in GB4, Kali Linux for WSL - 5.7k/18.7k. I assume this is at 25w...

AMD AMA - Starts at 12PM EST on Wednesday May 9

Interesting. I'll go test with Performance Bias off. So far, I only tested with CB11.5, CB15, and AIDA modes. A user at chiphell on SummitPI 1.0.0.4 had similar results on an 1800X with the same motherboard...

AMD AMA - Starts at 12PM EST on Wednesday May 9

Hello James, I have a question about cache latencies: It appears I own a 1600X with 12-cycle L2 latency, and "enhanced" L3 latency. (I have not tested AGESA before SummitPI 1.0.0.6). The CPU was manufactured in early 2017, and purchased last June. As far as you know, were there any Summit...

Ryzen: Strictly technical

A good 2600K was able to do 4.8-5 GHz+ on water cooling. I had one that was able to bench single threaded at 5.2 GHz on the stock dinky heatsink. Frequency wise, Intel has gone nowhere since 32nm.
