FAQ

Q: My processor is running 55C under load. Is this normal?

A: Safe CPU temperatures are 60 degrees Celsius and below. It may still run fine with CPU temperatures, exceeding 60C threshold by a few degrees. Running the FX-8320 close to 70 degrees and higher is not recommended.

Q: I have an AMD FX-8320 CPU. Can I upgrade it?

A: Probably yes. Processor compatibility is determined by your motherboard. Please check CPU-Upgrade.com website for CPU support list for your board.

The boxed processor is shipped in a tin can, which is identical to tin cans of FX-8120/8150 CPUs. Besides the CPU, the box contains processor installation instructions, and a good quality (good for stock processor that is) fan/heatsink with copper base and heatpipes.

News

AMD cuts prices of desktop CPUs

May 01, 2013: Earlier this week AMD announced new processors, expanding the line of high-end FX CPUs with quad-core FX-4350 and six-core FX-6350. It's not uncommon for AMD to lower prices when launching new products, and this time it was not an exception. Based on the latest official AMD price list, the company cut prices of ten A-Series and FX-Series chips by as much as 19%.

AMD plans to cut processor prices, launch A4-4000 APU

Mar 22, 2013: AMD Richland APUs are scheduled to launch at the beginning of June, at about the same time as Intel Haswell desktop CPUs. According to DigiTimes, prior to the launch AMD is going to reduce prices of FX microprocessors and A-Series APUs. The prices will be dropped by 8% - 15% on the following SKUs: FX-4300, FX-6300, FX-8320 and A-Series A6-5600K. It is possible that we may see lower prices for other APUs as well.

AMD FX-8000 CPU series: What is under the lid?

Jan 13, 2013: This is not going to be a long and boring article explaining different features of AMD FX microprocessors. Instead, we will have some fun actually looking under the lid. As you may know, top of the line FX-series processors are shipped in tin cans, which creates an illusion of more expensive, and consequently better quality products. The top lid of the can has an insert, that keeps the lid in place when it's closed.

AMD introduces second-generation FX processors

Oct 23, 2012: AMD today introduced second-generation FX-Series microprocessors, based on Piledriver microarchitecture. The released lineup consists of 4 products, having 4, 6, and 8 CPUs cores, and operating frequencies up to 4.2 GHz. The fastest processor in the series, eight-core FX-8350, has up to 15% higher performance than the former flagship FX-8150 model. Three other CPUs, FX-4300, FX-6300 and FX-6320, also offer better performance than their first-generation counterparts.

Prices of upcoming AMD FX microprocessors

Oct 18, 2012: Less than a week left before the launch AMD FX processors with "Vishera" core. The new processors will be faster than older "Zambezi" CPUs, although it remains to be seen by how much. The performance will be one of the factors determining success of new products. Another factor will be how well they are positioned against Intel Core i3/i5 lineups, and against AMD's older FX models, and this directly relates to their pricing.

AMD A-Series to launch on October 2, FX-Series on October 23

Sep 25, 2012: While Intel is almost done releasing new desktop processors for the rest of the year, AMD has only started. Next month we will see new lineups, based on the latest AMD Piledriver microarchitecture, which is a tweaked for better performance and power consumption Bulldozer architecture. A-Series "Trinity" Accelerated Processing Units will target budget / mainstream segments of the desktop market, and, according to SemiAccurate, they will be introduced on October 2.

Pre-order prices of AMD FX "Piledriver" CPUs

Sep 20, 2012: Next generation of AMD FX microprocessors is around the corner. Built on "Vishera" design, new FX chips will have from 4 to 8 CPU cores, and pack as much as 16 MB of combined L2 and L3 cache on a chip. The CPUs will feature better performance than the first Bulldozer models, partially due to more efficient "Piledriver" microarchitecture, and partially due to higher stock frequencies. The FX processors will be available in October, while some reports place the launch as early as October 1.

AMD FX-8300 and FX-8320 to launch in October

Jul 15, 2012: We previously reported on new AMD FX-8350 eight core microprocessor, coming in the fourth quarter. Due to improved micro-architecture and higher stock frequency, that part will offer moderate performance boost over current flagship AMD FX-8150. The FX-8350 is not going to be released alone. According to Fudzilla, AMD plans to launch FX-8300 and FX-8320 eight-core models together with the 8350.
