The A10-7850K is a fourth generation Kaveri CPU with an integrated GPU billed as AMD’s most powerful APU when it was released in January 2014. It combines four steamroller CPU cores and eight Radeon GPU cores. Despite it’s billing, raw performance proved to be underwhelming: the base/turbo clocks run at 3.7/4.0 GHz, leading to an effective speed of 63 which is actually lower than it's predecessor: the A10-6800K (full comparison). However combined with an SSD this would provide an acceptable experience for most desktop applications. The integrated R7 graphics are around 25% better than the 8670 Graphics in the A10-6800K. The A10-7850K makes for a reasonable entry-level gaming PC or HTPC. However if processing performance, especially single threaded, is required, then the i3-4360 is far superior. [Dec '14 CPUPro]

The FX-8320E is a Vishera eight core processor based on AMD’s Piledriver architecture. The ‘E’ in the FX-8320E denotes energy efficiency with the FX-8320E boasting a TDP of 95 Watts which is relatively low for FX processors. The FX-8320E was launched in September 2014 at the same time as the FX-8370E. Comparing the 8370E and 8320E shows that the performance profiles are similar with the 25% more expensive 8370E edging ahead, particularly on single core workloads. The 8370E is clocked slightly higher with base/turbo frequencies of 3.3/4.3 GHz versus the 8320E’s 3.2/4.0 GHz. Overall the 8320E scores a mediocre effective speed of 70. Whilst this is sufficient for the majority of desktop applications: web-surfing, word-processing and playing movies, better single-core performance is offered by any number of Intel processors. [Dec '14 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
