AMD Makes 2nd Gen Ryzen Processors Official With Availability Starting Next Week (hothardware.com)
MojoKid writes: Today AMD announced official details regarding its new mainstream second-generation Ryzen family of processors. Pricing and detailed specs show some compelling new alternatives from AMD and a refined family of chips to give Intel even more competition, especially considering price point. These new AMD CPUs are all based on the 12nm Zen+ architecture and, at least initially, include four SKUs. The Ryzen 7 family features 8 cores and 16 threads along with 20MB of cache. Ryzen 7 2700 (65W) has a base clock of 3.2GHz and a turbo frequency of 4.1GHz. The top-of-the-line Ryzen 7 2700X (105W) ups the stakes with clocks of 3.7GHz and 4.3GHz respectively. The new Ryzen 5 family features six physical cores capable of executing 12 threads and 19MB of cache. The Ryzen 5 2600 (65W) has a base clock of 3.4GHz and a max boost frequency of 3.9GHz. The Ryzen 5 2600X (95W) ups those speeds to 3.6GHz and 4.2GHz respectively. AMD says that the Ryzen 5 2600, Ryzen 5 2600X, Ryzen 7 2700 and Ryzen 2700X will be available starting April 19th, priced at $199, $229, $299 and $329 respectively.
Yeah, we call those "GPUs".

Sounds like what they have now, but the models that were X models are now base models. The 1600x is a 6 core that does 3.6 to 4.0. Now the 2600 is a 6 core that does 3.4 to 3.9. Hope I'm wrong and these new CPUs are amazing but from the looks of it this is just rebadging.
my karma will be here long after I'm gone
they've finally got within striking distance of Intel in single threaded performance (e.g. within 10%). And they blow Intel out of the water on Multi-threaded performance except for the highest end of Intel parts (e.g. the 7980XE outperforms a 1950x but it's 2x the price). Assuming this is right there won't be much point to buying Intel for gamers and (most) workstation users. The Ryzens we have today produce more stable frame rates (e.g. fewer 1% & .1% lows) thanks to the much better multi threading. Give them about 20-30% more single threaded performance with that advantage and it's going to be an AMD generation.

In tech jargon this is usually termed "bang for the buck".
You're welcome.
Honestly, I was expecting better. The whole point of modules is that you can copy-paste them. Why are they not putting three or four modules per chip yet? It's been almost a full year.
what would the everyday person do with that?
But have they fixed this yet? Their second bug in Linux?

C'mon, tell us the important stuff!
I'm betting Intel is throwing money at researchers to discover vulnerabilities on competitors products.
They are probably doing the same to their own products too.
stop shelling for intel
confused why this comment is +2, while the parent, which says exactly the same thing but with more detail and a link, is -1.
stop shelling for intel
yes, I agree.
its easy to fix, though; just type 'exit'.

You were being called out as a shill, and it does you no good at all to pretend otherwise.
One thing that might give Intel an edge is the upcoming AVX-512 extensions in the next cycle of processors. It'll allow two more registers for vector operations, along with a bunch more opcodes. It doesn't accelerate all operations, but what it does accelerate usually gets a pretty good speed boost. There's an HPC blogger that benchmarked the heck out of a couple of SSE/AVX/AVX2 chips, and each successive part increased some SPEC operations by 20-40%. Video encoding in particular got a good 30% boost from generation to generation - much more of a boost than the CPU optimizations alone.
Of course, AMD could clone these features, but they've been lagging in support for AVX. The Ryzen parts have half the AVX registers of the Intel chips. Sometimes they can make up for it through sheer parallelism, but not for every workload.

Didn't Intel produce processors in Israel at some point in the past? I'm sure there are some shared interests that can be dug up between this company and Intel

Intel CPU Backdoor Report
The goal of this report is to make the existence of Intel CPU backdoors a common knowledge and provide information on backdoor removal.
What we know about Intel CPU backdoors so far:
TL;DR version
Your Intel CPU and Chipset is running a backdoor as we speak.
The backdoor hardware is inside the CPU/Bridge and the backdoor firmware (Intel Management Engine) is in the chipset flash memory.
30C3 Intel ME live hack:
[Video] 30C3: Persistent, Stealthy, Remote-controlled Dedicated Hardware Malware
@21:43, keystrokes leaked from Intel ME above the OS, wireshark failed to detect packets.
[Quotes] Vortrag:
"the ME provides a perfect environment for undetectable sensitive data leakage on behalf of the attacker".
"We can permanently monitor the keyboard buffer on both operating system targets."
Decoding Intel backdoors:
The situation is out of control and the Libreboot/Coreboot community is looking for BIOS/Firmware experts to help with the Intel ME decoding effort.
If you are skilled in these areas, download Intel ME firmwares from this collection and have a go at them, beware Intel is using a lot of counter measures to prevent their backdoors from being decoded (explained below).
Backdoor removal:
The backdoor firmware can be removed by following this guide using the me_cleaner script.
Removal requires a Raspberry Pi (with GPIO pins) and a SOIC clip.
2017 Dec Update:
Intel ME on recent CPUs may be disabled by enabling the undocumented NSA HAP mode, use me_cleaner with -S option to set the HAP bit, see me_cleaner: HAP AltMeDisable bit.

Nope.
If they did, they wouldn't have held back the information that Intel is just as susceptible to the ASMedia bugs as AMD is. That Israeli con-job was an Intel-sponsored hit-job from start to end, there is no doubt about it. Just look at the material, including the interview Arstechnica did with them. Look at how they twist all over the place to avoid saying "Intel" for instance, and add to that all the other weird stuff in the "story". It just doesn't add up, unless you add "Intel" to the mix. If you insert that in all the blank spaces, it suddenly starts making sense.
Fuck the Jews.
but all shipping parts are vulnerable to spectre and the followons.
Remember that they are 2 different vulnerabilities named "spectre".
Spectre variant1 affects AMD as it affects virtually any CPU under the sun that does speculative execution.
But relatively to the other vulnerability, it's much more moderate, it's the CPU speculatively access data to which the current process HAS access anyway. (e.g.: getting pass a size check and reading from another array of the same thread).
There are very few corner case where a thread should not read data to which is normally has access to (mostly in situations of JITed 3rd-party provided code - e.g. Javascript downloaded from the web - running in the same context as some sensitive data - e.g.: you password manager plugin) and proper process separation is the correct long term strategy anyway.
Spectre variant2 abuses the way speculative indirect branching is done (jumping to a location which is not known in advance : jump tables like C++ virtual methods, some possible C's "switch" implementations, etc.), and it's extremely CPU dependant as each CPU has a different way to speculate that.
It's much more scary than Spectre v1, because one process of the attacker (e.g.: a program that the attacker has uploaded into an Amazon EC2 VM - something that he should be able to do), can cause an entirely unrelated process to speculatively jump and execute arbitrary locations (e.g.: the *hypervisor* handling that VM could be forced to jump to selected pieces of code, and thus doing some return-oriented-programming. Again that's the hypervisor we're talking about, a completely different piece of code to which the attacker should never have had access in the first place).
- On Intel hardware (Xeons), spectre v2 exploit have been demonstrated successfully by Google's project zero
- AMD hardware can do speculative branching (so AMD has marked their hardware as potentially affected), but as of today nobody has manager so successfully demonstrate a usable exploit, and the jury is still out whether this actually exploitable (might be that the peculiar implementation AMD CPUs use to branch speculatively cannot be abused in any useful way to begin with) (so AMD is still indicating exploitability as very probably unlikely).
So currently, on AMD you're still safe regarding Meltdown (AMD hardware doesn't read data it doesn't have actually access to), and Spectre v2 (there are probably no way to abuse indirect branch prediction to achieve anything meaningful).
