Sorry, I confused myself with all these benchmarks. I meant i7 7700K @ £340. That's the mainstream performance option at the moment that's what they have to compete against at that end of the market. The Intel's -E line CPUs are in a world of their own. Either which way, that's not neccessarily the point, it's that we shouldn't still be guessing how these CPUs are actually going to perform at this point. This much hy…

7700k is a 4 core / 8 thread. AMD appears to be pricing its 8 core / 16 thread chip at 480 USD which is about 390 GBP. So if the leaked pricing is anywhere near reality (and I'll admit that's contentious), then it's a no brainer in favour of AMD. On the leaked pricing, some are expressing cynicism, but remember that AMD pays big penalty fees to Global Foundries if it doesn't meet long term contractual volume requirem…

I would chose superior performance with 4 core, because I expect my workload to be mostly single-core, so 4 more cores won't make me that happy. But for those, who can load those 8 cores, it's awesome deal.

If amd reveals the details now, Intel will react with better price/perf before you can but an AMD chip.

I'd be very surprised if Intel doesn't have running Ryzen silicon in their Labs right now.

As I used to work for Intel, I can tell you: absolutely not - this would expose Intel to far too great risks on antitrust level.

However they do pay 3rd parties to run parallel benchmarks on both their silicon and competitors, and get access to detailed reports. And probably they will buy silicon off the market when it's available commercially.

Maybe a big L2 cache is nice, but overall performance is all that really matters. I suspect the figures we have seen are from running the chip hot with a fancy cooler. Gamers won't be able to overclock much and regular people will have heat and noise to deal with. Just a hunch, we'll see in a few weeks. I'm going to buy a ryzen setup if they are not awful.

I think they could carve out a niche by being the chip maker that produces a trustworthy computing environment that supports blob-free computing without the equivalent of Intel Management Engine. That plus your point about TCO could be a nice way of competing with Intel.

AMD has their own thing called TrustZone[1]. If you read past the marketing speak it is made to allow software to run without the user being able to poke at it. I assume this is for DRM, but who knows what is running there. [1] https://www.amd.com/en-us/innovations/software-technologies/...

Yes indeed. The current landscape (at least as I glean from the Core Boot people) is that AMD is at least as bad if not worse than Intel.

So the latest AMD cores seem like they might be more competitive... does anyone know which AMD processors are likely to support ECC memory? My one big gripe with Intel CPUs is that they currently only support ECC memory for non-consumer chips. I run a personal ZFS cluster and am more concerned about data integrity / cost than I am about pure CPU performance.

I think that most AMD processors support ECC.

The catch appears to be finding a motherboard to do it.

a big l2 cache will tend to lead to good overall performance. In that it will positively impact the performance of a wide range of programs. Especially ones that adhere to common OOP or functional programming practices. (Pointer hopping, virtual functions, linked lists, etc)

Games or other carefully tuned programs that carefully lay out data in memory may not be much affected I guess.

Getting a bit bored of leaks, press releases and even specs. The proof of a CPU is in how it benchmarks across real workloads. We're 2-3 weeks away from global release. People buying components NOW are exactly the sort of people AMD should be working their socks off to stop buying Intel parts. But instead of any firm performance figures, we have rumour. The only reason I can imagine AMD is still keeping the press und…

"The proof of a CPU is in how it benchmarks across real workloads."

Define 'real workload' here. Are we talking about a workload where the compiler specifically optimizes for Intel, or where the executable chooses unoptimized paths if it finds anything other than intel processors inside?

Because I've found that when it comes to raw x86, no SSE anything or other nonsense; pure, unadulterated original x86, AMD simply owns.

> AMD said its upcoming Zen x86 core fits into a 10 percent smaller die area than Intel’s currently shipping second-generation 14nm processor. We need to compare apples to apples. AMD's Zen chips have no IGP, while most Intel chips are shipping with an Intel GPU. If you look at an Intel die shot, about half of the area is taken by the GPU.

I strongly doubt AMD are specifically targeting the desktop/laptop CPU market. * Cloud computing has an absurd market cap.[1] * Ryzen has some features that specifically target cloud computing: * * More PCIe lanes than a Xeon. These are basically useless for desktop/gaming (as SLI doesn't scale beyond 2 cards). This shines for cloud computing because you can fit more GPUs in a blade. There's also ML to consider. * *…

"SLI doesn't scale beyond 2 cards"

Guess you weren't around in the days of Quad VooDoo 2 GPU rigs. They most certainly did scale. nVidia and AMD's implementation? Nope. They screwed the pooch with that one and will never recover until they learn that the older way was indeed better.
