Intel: AMD Weak On Battery-Powered Laptop Performance - But DPTF On Linux Still Suck

i've read your marketing material. and replied with 1200 hz tv. you can continue your quest for truth here https://en.wikipedia.org/wiki/Clock_...urrent_records

I never said anything about a TV, that was you... Duh...

This is what you just did...

Oh to have paranoid schizophrenia (I don't know that feel but you sure do).

...and speaking of brain-dead, mouth-breathing, room-temperature-IQ types--

Caught one !!


You don't know "...that feel..."? You obviously don't know basic grammar, either. Perhaps you need to employ the services of someone who graduated from Junior High School to proof your "offerings" before putting your stupidity and idiocy on display. On second thought--just keep doing what you're doing; the entertainment is...different.

And you are also not a fan of reading apparently

I can get up to 10 hours on my ASUS Zephyrus G14 wile still having desktop level performance when connected to AC. And this is the same on Windows.
Marketing will not fix you CPU-s Intel :P.

you are also not a reality fan. what twice the clock? do you also believe in tv 1200 hz?

And you are also not a fan of reading apparently... Let me just re-quote what I've already quoted...

The processor does ALU operations with an effective latency of one-half of a clock cycle. It does this operation in a sequence of three fast clock cycles (the fast clock runs at 2x the main clock rate) as shown in Figure 7. In the first fast clock cycle, the low order 16-bits are computed and are immediately available to feed the low 16-bits of a dependent operation the very next fast clock cycle. The high-order 16 bits are processed in the next fast cycle, using the carry out just generated by the low 16-bit operation. This upper 16-bit result will be available to the next dependent operation exactly when needed

I'm by no means an Intel fan, but actually Intel did accomplish that goal, at least superficially... Netburst architecture used integer units running at twice the core clock and the core clock got up to the mid-4ghz range, so yeah those integer units got to nearly 10ghz...

There are quite a few Tigerlake reviews in the net and indeed the performance difference between AC and battery mode seems to be (surprisingly) low in most of them. If AMD prefers a bigger slow down in favour of a longer battery life time Intel has a point. I mean usually all performance tests are done in AC mode and battery life tests obviously in battery mode. This is something to look at it in future tests.

It's been a few years and I didn't quite remember the details of their implementation, but that's indeed very elegant for Intel. Too bad it didn't amount to anything because the P4 was eaten alive by the Athlon.

Seems like the days of "speed demons" are over though. Wide cores are the future.

Yeah it did, Athlon Thunderbird and up had three integer units per core and had a really sophisticated fast path. P4 had two integer units per core and could only put a very limited subset of x86 on the fast path. Athlon could put far more code on the fast path than P4 could.

So all types of DDR encode both edges of the clock, hence the name. Intel's Netburst architecture even encode both edges of it's internal busses. Which presents a problem, the buss carries twice the amount of encoding than what an equally clocked integer unit can process. They had an option to either buffer the hell out of the buss or double the clock of the integer units. Buffering the hell out of it would have increased latency too much so they chose to double the clocks....

Am I the only one who picked up on the use of a now-socially-unacceptable term, by no less than the esteemed owner of this website? To wit:

"Intel: AMD Gimps On Battery-Powered Laptop Performance..."

"...to basically plead their case that AMD Ryzen laptops are gimping on battery-powered performance..."

If I'm not mistaken, "gimp" is one of those words which is now verboten, thanks to the brain-dead, mouth-breathing, room-temperature-IQ SJWs.

From the holder of a MASTER'S DEGREE, who is a MASTER ELECTRICIAN, and who teaches MASTER-SLAVE flip-flops in a logic design course...and who will never cave in to all you pathetic, social-justice-seeking queerdos and LBJQMNORST...effetes who have no real work to do, except to agitate; and tell the rest of us how you THINK we should act. For all of you, I have a parting, sincere, heartfelt suggestion: fuck you, AND your agendas.

And find a real job. If you had to be at work at 8 in the morning, you wouldn't have time for the shit you spread.
