FM2 FAQ Q: Does this processor support the dual graphics feature? A:
Yes. Q: What GPUs are supported in dual-graphics mode? A: AMD
recommends Radeon HD 6450 graphics card. Radeon HD 6570 discrete
Graphics Processing Unit is supported too. Q: I have an AMD A6-6420K
CPU. Is it possible to upgrade it? A: Probably yes. Processor
compatibility is determined by your motherboard. Please see website for CPU support list for your board. A6-6420K
Overclocking Sorry, overclocking information is not available at this
time. Related news stories AMD quietly releases "Richland" A4- and
A6-Series APUs Mar 05, 2014: Back in January, AMD launched the first
"Kaveri" APUs, featuring the latest "Steamroller" architecture with
improved per-clock performance. The chips also incorporated newer
Radeon R7 GCN graphics unit, that added support for Heterogeneous
System Architecture. The processors had 4 CPU cores, and were priced at
$150 and higher. Less expensive dual-core "Kaveri" APUs are planned to
be launched in the second quarter, and in the meantime AMD prepared
several budget "Richland" models, including A4-4020, A4-6320 and
A6-6420K. AMD to launch A4-4020 APU, desktop Athlon and Sempron
SoCs Dec 19, 2013: Recently leaked AMD desktop roadmap stated that next
year the company will introduce low power "Kabini" systems on a chip
(SoC), and release new mainstream APUs, based on "Kaveri" core. Only
quad-core "Kaveri" products will be available at launch, and dual-core
mainstream processors will be built using older "Richland" core. Prices
and brief specs of all these microprocessors were published last week
by, they also revealed new A4-4020 "Richland"
SKU. Pre-order prices of upcoming AMD Kaveri and Richland APUs Dec
07, 2013: AMD is getting ready to launch in January two Kaveri
Accelerated Processing Units, that, by some reports, should boost both
CPU and GPU performance by up to 20% - 30% compared to A10-6000 series
APUs. Model numbers and specifications of new Kaveri processors emerged
last week, and the A10-7700K and A10-7850K chips are now available for
pre-order in US. Based on the pre-order prices, the processors are $12
- $34 more expensive than boxed A10-6800K products. What's more,
unheard of before A4-6320 and A6-6420K dual-core APUs are also
available for pre-order. Compare AMD A6-6420K benchmark results with
