Which is still a 1.2 GHz base clock.
- read_if_gay_ 7y agoBecause wasting energy on a 4 GHz base clock is completely pointless (and so is your criticism) if you can adjust frequency as needed. 99% of the time 1GHz is sufficient. It’s only when you launch the browser that a faster CPU is useful, not when you’re reading through a website
- enraged_camel 7y agoThe problem is that it ramps up by 250 Mhz increments, over a period of several seconds, and that can be extremely noticeable in some workflows. I went from an 6700HQ (2.6 Ghz base) to a 10710U (1.1 Ghz base) and the difference is definitely there, and it's jarring enough to the point where I kind of regret it. It feels like a huge step backwards, despite the latter CPU being four generations ahead.
- exhaze 7y agoDid you make sure that your turbo button was pressed? Honestly, this is why I just stick to naturally aspirated CPUs.
- dijit 7y ago> The problem is that it ramps up by 250 Mhz increments Isn't this completely down to the cpu frequency governor in the OS? My impression was that this "stepping" is customisable, at least in linux, I regularly step my CPU manually even. I'm not sure what Apple has here, but maybe it's not what you expect.
- enraged_camel 7y agoI'm on Windows 10 and I'm not aware of a built-in method to change the CPU multiplier.
- dijit 7y agoHow windows does things and how other operating systems do things, in the wise words of Jayne Cobb "ain't exactly but similar".
- sfshaw 7y agoThe first thing I notice in that comparison is that one chip is rated for a 45W TDP and other is 15-25W. While I think these cross-segment comparisons are exciting and show great progress, it's just not fair to the electrons.
- read_if_gay_ 7y agoSurprising. What device are you using? This does not seem to be the case for my i7-8565U nor my older m3-something. The 8565U for example feels just as snappy as my desktop i7-6700, except it’ll throttle after about 30s.
- gohbgl 7y agoWith modern noteboock CPUs the base clock is only a loose indicator for how a CPU will perform. The CPU will still be downclocked and undervolted depending on the load.
- kllrnohj 7y ago> Because wasting energy on a 4 GHz base clock is completely pointless That's not how base clock works. Base clock is not min clock. Base clock is what it's "guaranteed" to hit under sustained load if TDP is respected. It's the TDP clock. A 4ghz base clock CPU will still be far, far below that when idle.
- calibwam 7y agoDon't you know? Higher is always better! 5 Ghz in my laptop, plz!
- mrpippy 7y agoAnd turbos up to 3.8 GHz. We’ll see, but I suspect it’ll spend a lot of time above 3 GHz
- ksec 7y agoAt a 9W TDP the chip wont spend any more than a few seconds at boost clock.
