Intel Says New 'Sierra Forest' Chip To More Than Double Power Efficiency 28
Intel says its upcoming "Sierra Forest" data center chip due out next year will have 240% better performance per watt than its current generation chip. It's the first time the company has disclosed such figures, notes Reuters. From the report: The company is for the first time splitting its data center chips into two categories: A "Granite Rapids" chip that will focus on performance but consume more power, and the more efficient "Sierra Forest" chip. Ronak Singhal, a senior fellow at Intel, said the company's customers can consolidate older software onto a smaller number of computers inside a data center.
"I may have things that are four or five, six years old. I can get power savings by moving something that's currently on five, 10 or 15 different servers into a single" new chip, Singhal said. "That density drives their total cost of ownership. The higher the density, the fewer systems they need."

I'm left wondering why they haven't been better at performance/W before now. If they've suddenly found 240% savings, what the hell have they been doing wrong all these years?
Those power efficiency gains are easy to achieve if you a) use a more advanced processing node, b) optimize the core design for efficiency, and c) reduce the clock frequencies. Now the question is, will "Sierra Forest" be as fast as the previous generation?
Looks like "Granite Rapids" will be the performance chip and "Sierra Forest" will be for efficiency. It is great to have this as an option but I wouldn't expect "Sierra Forest" to break any benchmarks -- at least those benchmarks that ignore efficien

You have a reading disability. None of what you said in any way invalidates the claim that this is the first time Intel has marketed a future product in relation to performance per watt over a current product.

This is about the datacenter market, and, specifically, bringing over a concept already in the desktops.
Effectively, you can either get a single thread behemoth with AVX-512 and all the trimmings (basically the "high performance" chips is made of what might be considered equivalent to a "P core" in Intel's hybrid architecture). You will have a lot of cores, but the cores will be fairly beefy.
In the 'efficient' offering, it's basically "Ooops, all E cores". Lower clock and less function, but more cores (ho

But as we've seen with ARM in servers, many workloads is exactly this, a few microseconds on the chip per click/thread/page hit doesn't need a ton of power, you just need to process/store/retrieve a small amount of data but across many thousands of clients per second.
The actual 'scientific' workloads where current Intel chips shine above all others is a very small part of the modern server market. Sure, back in the day when your LAMP stack was on a single server, this was relevant, now with microservices ev

At what cost? (Score:4, Interesting)
What they don't say is they achieve this by producing a CPU with only E cores each having about a third of the single thread performance of a normal P core only Xeon processor. No AMX or AVX512. They are simply lowering cost per watt by dramatically reducing performance per core. It comes down to your applications whether or not this kind of tradeoff is worthwhile. At some point you will probably run into a wall where applications in this category are increasingly better served running on GPUs with far better performance per watt than anything intel CPUs can deliver.

They're taking this tech from the mobile chips - it's just a nerf'ing of core and instruction capabilities. There's nothing special about it.
If you want power/efficiency while retaining performance, you'll have to get off the archaic Intel architectures and move to ARM.

A lot of workloads are such that ultimate performance isn't needed - after all, if you're just tossing up files that doesn't need much performance since each core can handle many users at once.
