I didn't get it.

What's that suppose to mean?

Benching servers?

[rtsurfer]

Is AMD gonna grab Intel by the p**** here...??

 

God, I hope so...

[Lucky_n00b]

inb4 there's media writing article that "AMD Zen allegedly will reach 2000 Cinebench R15"

[flanker]

Its possible, for 8c/16t CPU. But depends on clocks (OCed or not? Propably OCed, but how much?)

Some leaks appearing

Notes:

• There are some errata issues present in the current testing samples, similar in a way to the TLB bug of the Phenom. The workaround right now is done via the BIOS. The workaround however, strips around 30 ~ 40% of the CPU performance.
  
• The CPUs are well behind schedule and every day there's real progress and bug fixing being done. Unlike with INTEL's E0 CPUs which make it to the wild that are almost completely final silicon. AMD's samples will continue to get bug fixes right up until retail spec sampling to partners.
  
• In August Clock speeds were 3.8GHz, right now 4.2GHz overclocking is possible, with LN2 5GHz is doable. Again this will change of course, but it is just the current silicon that is behaving like this.
  
• AM4/ZEN uses an SOC design, that means even CMOS/BIOS configuration is on package (not necessarily on silicon, I can't confirm this) so it is possible to clear the "BIOS" and still have old value applied 30 minutes later. How this will be addressed remains to be seen. Perhaps it won't be the same scenario for final silicon
  
• Operating voltages (nominal) are 1.3v and all the way up to 1.5v should be fine it seems for AIO cooling. Frequency scaling isn't a strong point but again that may have everything to do with the process at this point rather than an inherent design limitation.
  
• Performance is particularly strong at this point vs. INTEL's latest offerings. Single thread performance is matching Haswell-E and of course multi-threading performance as well. Tests that are memory bandwidth dependent may go to the INTEL platform simply as a result of having more memory channels, but I can't confirm that right now and have no info on that. The important thing here is that the 16Thread/8-Core CPU is minimum 5960X performance if not better actually. (Based on Cinebench R15) with the error fix disabled.
  
• Can't speak to how well the IMC is working as current samples are locked to low DRAM frequencies (2133MHz and lower) and of course this has an impact on performance.
  
• As stated in the beginning, every week is progress and AMD is working at an unprecedented rate to get these ready by March.
  
• You're unlikely to see any high end boards for the CPUs prior to launch or at launch, simply because no vendors can commit to too much right now as plenty is changing at a rapid rate.
  
• All overclocking is done via Overdrive, you can't change any performance features at all in the BIOS (on to that next) at all.
  
• BIOS or UEFI is actually built into the CPU, so only AMD can update the "BIOS" or microcode. All overclocking must take place within the Operating system
  
• Right now it takes up to 30 minutes to clear the BIOS. If you remove the CPU and place it on another motherboard, it'll have the same settings applied as on the previous board. So debugging is a nightmare
  
• 6850K SKU (May not be final designation) is wait for it.... $300 roughly. That's 8 Cores and 16 Threads
  
• AMD's Hyper Threading is called SMU and it is ************ good. The same efficiency as Intel's HT.
  
• Performance is really good, be it SuperPi, Cinebench, 3DMark etc, it's FPU performance is incredibly good and easily matching that of what Intel offers.
  
• Current performance is staggering even though it is limited to 2133MHz (as mentioned before) and NorthBridge Frequency is limited to 2400MHz
  
• There will be a nigher SKU than the 6850K, but it is a higher bin so it will certainly overclock better than 6850K and that may carry a premium price, but unlikely to be double.
  
• There's plenty of excitement from all board vendors about the platform, so we will see how it all pans out. (Especially with the hot mess that INTEL has in store for us H2 2017, that we can leave to another thread)
  
• For Gaming, the CPU is neck and neck with INTEL, even at low res where CPU bound.

 

Not all is correct, but the important stuff seems relatively accurate

The BIOS onto CPU thingy has been debunked by TheStilt, I'll link later

Sorry to disappoint, but the consensus(according to Stilt & a few others) seems to be that majority of that 'info' is BS

I don't spend as much time on forums as I used to, it's been a while since I saw a thread discussing rumours/discussion/arguement for a new CPU or GPU architecture!

 

Does every new release still get rumoured half to death?

[DrWeez]

Does every new release still get rumoured half to death?

 

only the AMD stuff..... tall stories... little follow through

[flanker]

we will see, AMD can only surprise. Its not much posible, the Zen cpuld be worse than Vishera (lol)

[Splave]

Zen is great dont worry

[flanker]

[der8auer]

overpromise and underdeliver

 

I always lower my expectations so AMD can amaze me

 

On a serious note: I hope that Zen will perform great. The industry needs competition.

[Massman]

I can't believe they still have FX8300 on there

[Massman]

[flanker]

FX-8300 maybe ebcause it is 95W version and the price/performance ration is still solid (specially in multithreading)

[rtsurfer]

Zen is great dont worry

 

[flanker]

the rumours writing about really good single thread for AMD CPU, so maybe finally after some years...only few months and its here. I suppose some demo at CES+boards and in next monthx after could be CPU launch.

[Splave]

 

if you are slow, just add more cores right?
