Default Intel and the 800 MHz 7W SDP

Quote:
Today, Intel confirmed to us that though chips like the new Core i7-3689Y run at their advertised 1.5GHz in a system with 13 watts worth of cooling, and turbo up to 2.6GHz when things stay cool enough to do so, they're much slower at stock clocks. At 7 watts, Intel told us, the Core i7-3689Y runs at only 800MHz by default.

I think anyone would agree that 800MHz base frequency is not something to be proud of. It seems nothing about this number was announced at CES.

Nor, as theverge states, is it mentioned at intel's site: http://ark.intel.com/products/72015/...2_60-GHz?q=i7-

$362 for 800 MHz dual core?

800mhz i7 is still pretty powerful compared to anything in that power envelope.

Why not? Why do you need a chip running at full speed when there is no work to be done? How do you think they can fit into such a tight thermal/power spec without aggressive Speed Step?

SDP or TDP?

Because this isn't a C state? This is the base frequency (aka, the non turbo speed).

Which is a feature. Low power chips have always commanded a premium - who's to say the final applications need more than 800MHz (with 1.5-2.6GHz turbo when available)?

guess I fail at reading but still, it should still be more powerful than anything under 15w.

800 MHz base frequency as a feature? What fraction of a percent duration are you going to hit turbo with a 7W heat sink?

What will these features be advertised as? i7-3687Y's? The ones that run at 1.5GHz and get xxxx in benchmark yyyy?

It will be interesting to see how it stacks up compared to a $50 Kabini.

This, I can not argue with you on, IPC wise it will probably trump anything else that is 800 MHz in that power envelope, but there are very few things with that low of frequency in that segment. I could say that I am very curious to see how it compares with Kabini, but beyond curiousity and fun number crunching, it would not matter to me. The difference either way would not justify the price in my opinion.

Price can be argued but is really subjective. I can say that there is no place for a 350 dollar chip in that segment, someone else can say that they want to pay 2 or 3 times as much for a tablet because it says i7 on it. Personally, I don't think there will be demand beyond "hey look at me and how cool and 7W I am", but people have done dumber things.

My real concern is misleading marketing on intel's part. Last year it was a fake video iGPU demo, this year it's leading everyone to believe 1.5 GHz at "7W". I bring up the topic originally because it seemed that nobody is aware that 800 MHz is the actual frequency.
