AMD FX-8320E (Vishera) 8-Core Processor Review

The AMD FX-8320E – not something that’s exactly new but in fact it’s actually quite old as the Codename Vishera for AMD’s Piledriver core based FX series processors surfaced many years ago. The thing about the FX-8320E is that it’s improved with lower TDP, from a whopping 125w down to 95w.

Processor Details

Here’s the CPU-Z capture.

Everything is essentially as the other FX-8xxx series, so the FX-8320E is exactly the same processor as the FX-8320 released 3 years ago (in 2012) running at lower power consumption.

Let’s cut to the chase – benchmarks! Oh but before that, I managed to overclock the processor to 4Ghz with vcore at around 1.2.

Test Setup & Overclocking

Motherboard ASUS Crosshair IV Formula
RAM Avexir Blitz 1.1 8GB kit, set to 1333Mhz
Graphic Card ASUS HD 7750
Cooler Stock / DeepCool Gamer Storm Lucifer
Power Supply Cooler Master V700
Operating System Windows 8 Pro 64bit


The following are the test results. Note that there’s the STOCK setup and there’s the 3.5Ghz setup where the frequency is fixed, this is to see how it actually performs without fluctuating clock.

The source video is a 720p MKV file that is 90 seconds in duration. x264 settings at the slowest.

CPU Time Taken
AMD FX 8320E stock 234 seconds
AMD FX 8320E 3.5Ghz 215 seconds
AMD FX 8320E @ 4Ghz 202 seconds
AMD FX 8350 192 seconds

The overclock gave the Pentium a significant boost in performance but it’s still no where near the capability of a Core i3 with 2C / 4T.

Default settings

AMD FX 8320E stock 509
AMD FX 8320E 3.5Ghz 556
AMD FX 8320E @ 4Ghz 599
AMD FX 8350 633


Speed of archiving some almost 1GB worth of CR2 and MOV file.

CPU Time Taken
AMD FX 8320E stock 52 seconds
AMD FX 8320E 3.5Ghz 46 seconds
AMD FX 8320E @ 4Ghz 45 seconds
AMD FX 8350 50 seconds

While it’s beyond my explanation on how the FX-8320E and FX-8350 exchange blows, it’s good to see that the FX-8320E does give the FX-8350 a good challenge.

Power Consumption

Power Consumption measurement is based on readings taken from watt-meter. Power consumption is based on entire system, comprising of the processor, a motherboard, 2 sticks of RAM and 1 fan for cooling purpose. For this setup, the power consumption is inclusive of the HD 7750 graphic card.

Condition Peak (W)
Idle 56
Prime95 In-place Large FFT 136
Video Conversion 123

Temperature’s lab temperature is set at +/- 25°C

CPU Temperature (°C)
Idle 35
Load (Stock fan setting) 54
Load (Silent fan setting) 61

The stock heatsink handled the 4Ghz @ 1.20 vcore overclock fine BUT the processor is throttled quite often. Basically it works, the fan will be at full RPM once the temperature peaks and the processor down-clocks to 1.7Ghz – 2Ghz range from time to time.

I’m quite surprised at the temperature level because on stock settings the stock heatsink doesn’t feel hot, which is very unlike the 125w AMD FX processors and APU.

The Verdict

It’s not new and it’s not revolutionary either but it’s a great step ahead. You now have an 8-core 3.5Ghz processor solution at under RM 600, the processor retails at around RM 570. 🙂 It performs very close to the 125w FX-8350 that’s priced at around RM 700. A decent 970 chipset based board like GIGABYTE’s 970A-DS3P retails at around RM 310 and you have a great setup for under RM 900, much cheaper than having an Intel Core i7 with Z97 board setup.

I think the FX-8320E would be a great option for gamers on a budget, the only overclockable setup that’s under RM 900! For non-gamers, it works great too but you’ll need to add about RM 100 to the setup cost for a graphic card.
