Re: AMD Latest Llano APU Structure - GIGABYTE A75M-D2H Review
CPU is AMD latest A8-3850. There is another model, A6-3650, in the market. It’s also Llano APU structure.
The core name is Llano, 32nm, TDP 100W, clock 2.90GHz and 4MB L2 Cache.
In L2 cache, it’s higher than Phenom II 2MB, but it’s no L3 cache.
Performance Test
CPU 100.0 X 29 => 2900.1MHz
DDR3 1866.8 CL8 10-8-27 1T
GPU 600MHz
Hyper PI 32M X 4 => 22m 43.084s
CPUMARK 99 => 453
Nuclearus Multi Core => 12559
Fritz Chess Benchmark => 15.08/7240
CrystalMark 2004R3 => 204026
CINEBENCH R11.5
CPU => 3.46 pts
CPU(Single Core) => 0.88 pts
PCMark Vantage => 12276
Windows Experience Index - CPU 7.3
A8-3850 double L2 cache and no L3 cache compare to Phenom II. The performance is similar.
Even though phase in 32nm is exciting for AMD fans. However, they might be upset for same performance.
I do hope Bulldozer 8Core CPU can show users the leap improvement.

FM1 DDR3 spec is 1.50V. CPU in default clock, memory can reach DDR3 1866 which is improved.
You can see the performance improve most from DDR3 1333 to 1600. From 1600 to 1866, the improvement is much less.
For DRAM bandwidth, it’s weak point for AMD for many years. They should try to solve this issue soon…Comment
