AMD Announces Ryzen 5 Processors With 4 and 6-Core Chips Starting At $169 (hothardware.com)
MojoKid writes from a report via HotHardware: Today, AMD unveiled additional details with respect to the entire Ryzen 5 processor line-up. Unlike the Ryzen 7 series, which consists entirely of 8-core/16-thread processors, the Ryzen 5 family has two tiers consisting of 6-core/12-thread and 4-core/8-thread processors. The entry-level part is the Ryzen 5 1400, a 4-core/8-thread CPU with base and turbo clocks of 3.2GHz and 3.4GHz, respectively. The Ryzen 5 1500X has the same quad-core configuration, but with base and turbo clocks of 3.5GHz and 3.7GHz, and also has support for an extended XFR frequency range of up to 3.9GHz. The Ryzen 5 1600 is a 6-core/12-thread processor, with 3.2GHz base and 3.6GHz boost clocks. And at the top of the stack is the Ryzen 5 1600X -- which has a similar 6-core configuration -- but cranks things up even further to 3.6GHz/4.0GHz. With XFR, the absolute maximum frequency for all of the Ryzen 5 processors will be somewhat higher, but AMD hasn't disclosed specifics for all parts. AMD's Ryzen 5 processor line-up will work with the very same AM4 platform as the higher-end Ryzen 7. Ryzen 5 series processors will be launching officially on April 11, with prices starting at $169 for the Ryzen 5 1400. An additional $20 will get you a Ryzen 5 1500X, while the 6-core Ryzen 5 1600 and 1600X will sell for $219 and $249, respectively.
That's usually how it works these days. Intel even switches off entire perfectly working features. AMD at least does it much less so.

Unfortunately, it seem as if these 6-core and 4-core Ryzen 5 CPUs are only going to be eight-core Ryzen 7 CPUs with cores disabled in both compute-complexes.
The R5 1600X and 1600 are going to have one core disabled per compute-complex (CCX): 3+3. This was expected.
However, surprisingly, AMD has told Anandtech and Ars Technica that the R5 1500X and likely also the R5 1400 are going to have two cores disabled per CCX: giving it a 2+2 config.
When clock and IPC have been taken into account, Ryzen's biggest performance bottleneck compared to Intel has been shown to be when threads on different CCX'es are accessing the same memory. Each CCX has its own L3 cache and there is an interconnect between the CCX'es L3 caches which while being slower than a single shared L3 cache is somewhat faster than going to main memory ... but the L3 caches are only victim caches to each core's L2 cache - and therefore not necessarily caching the entire working set.
This means that the 1500X and 1400 are going to be slower on many workloads than on a hypothetical Zen CPU with one single four-core CCX.
It is believed that this bottleneck is the reason behind relatively low Ryzen 1800X/1700X/1700 scores in many games - compared to Intel (even when clock speed and IPC have been taken into account).
(Curious enough, this is also a known issue among programmers for the XBox One and PS4 - both having AMD CPUs with a similar setup, but apparently it didn't really occur to game programmers that AMD would have a go at retaking the desktop?)

Pssst....WSUS Offline or Autopatcher and Bob's your uncle...oh and you're welcome ;-)
ACs don't waste your time replying, your posts are never seen by me.
Well AMDs thermal envelope is half of Intel's with Ryzen. Not to mention 3x treads for the same price.
So, it would be really retarded move to buy Intel atm.
Intel CPU Backdoor Report (Updated Mar 13, 2017)
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.

"DAGGER exploits Intel's Manageability Engine (ME), that executes firmware code such as Intel's Active Management Technology (iAMT), as well as its OOB network channel."
"the ME provides a perfect environment for undetectable sensitive data leakage on behalf of the attacker. Our presentation consists of three parts. The first part addresses how to find valuable data in the main memory of the host. The second part exploits the ME's OOB network channel to exfiltrate captured data to an external platform and to inject new attack code to target other interesting data structures available in the host runtime memory. The last part deals with the implementation of a covert network channel based on JitterBug."
"We have recently improved DAGGER's capabilites to include support for 64-bit operating systems and a stealthy update mechanism to download new attack code."
"To be more precise, we show how to conduct a DMA attack using Intel's Manageability Engine (ME)."
"We can permanently monitor the keyboard buffer on both operating system targets."
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.
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).

Many of the new Ryzen chips have unlocked multiplier, so can probably get theme very close to Intel's power consumption by overclocking.
