[techreport] AMD FX-8300 rumored next week

95w, but base clock is 3.3Ghz. Turbo is still 4.2Ghz

Price is $199

At $169, I would still go with the 8320.

Just delivering a message.

IMO, the FX-8350 should be $169

The 8320's have been hovering in the low $150's for a while now at Amazon - currently $153...http://www.amazon.com/gp/product/B009O7YU56/ref=ox_sc_sfl_title_5?ie=UTF8&smid=ATVPDKIKX0DER

Could you not just under-volt and lower the clock speed on an 8320 to achieve 95 watts?

 

[Vesku]

Sure, but AMD isn't guaranteeing your 8320 will perform properly at ~95 watt settings.

CPU-Z shows max TDP on a processor, but not the current watts being used. Is there a utility that will show this?

CPUID Hardware Monitor has a Wattage indicator in 'Powers' under the CPU - I have been told that this is not accurate at all. Any ideas on this?

 

[Vesku]

The most reasonable option is to get a ~$20 power at the plug meter.

Oh, jeez...no wonder AMD cut orders to GloFo...they can't give these things away

They've certainly had a hard time convincing OEMs that they want the 125W versions, the enthusiast market was pretty brisk at launch.

AMD's TDP specs don't mean crap.

 

[BD231]

Long ago IDC went deep into this TDP thing, stating only Intel's TDP was accurate and that AMD based their TDP on something completely different ... wish I bookmarked stuff .

Some interesting info wrt TDP and FX from AMD guru Stilt @ XS :

FX-8300 should be exactly the same 'bin' as FX-8350

Vishera can operate at very low voltage after even a minor drop in frequency.

I recon the FX-8300s have 1.225V - 1.275V VID fuse for the base frequency, depending on leakage.
FX-8350s usually have 1.325V - 1.375V.

Most of them if not all.

To fit in 95W TDP slot a FX-8350 requires around 0.1V undervoltage (vs. PS0 Fuse VID).
The PS0 Fuse VID already contains a hefty margin as the loadline specification allows massive undervoltage.
The allowed amount of undervoltage depends on the leakage as the loadline slope is in relation to current draw.
With a high leaking part I have seen up to 60mV undervoltage with the default slope.

On average with FX-8xx0 -series CPU:

At 3500-4000MHz - 100MHz increase or decrease in frequency (with the same voltage) is worth of 2W in Pmax.
At 4100-4600MHz - 100MHz increase or decrease in frequency (with the same voltage) is worth of 2.5W in Pmax
At 4700-5000MHz - 100MHz increase or decrease in frequency (with the same voltage) is worth of 3W in Pmax

The leakage is thermally induced so it increases (or decreases) along with the temperature.
