Thread: AMD Aviii-3870K unsecured Llano Quad-Core APU

When AMD initially freed their Llano-based A-Serials APUs, the company pointed price-conscious client expecting for highly-incorporated, simple to assemble answer for an entry-level or mid-rate Computers. At the time of establish, the flagship eaxmple in the A-Series line-up was the A8-3850, which featured quad CPU cores paired to a DirectX-11 Radeon graphics processing unit with 400 active shader units. In our coverage of the A8-3850, we found it to offer nice function for its cost, especially in graphics-associated workloads where the APU’s relatively strong incorporated GPU was capable to stretch its legs.


The aboriginal A-Series APU agency did not affection any enthusiast-targeted products, but AMD bound responded to the A-Series’ generally favorable accession with a fresh flagship, dubbed the A8-3870K Black Version, which we will be assuming you really now. In its absence configuration, the A8-3870K is a slight advancement from the A8-3850, acknowledgment to a baby access in its absence CPU frequency.


The “K” in its allotment number, however, agency the dent is unlocked, which makes for some absorbing overclocking. When commutual to the appropriate motherboard, which appearance an adapted BIOS / UEFI that absolutely supports



the A8-3870K, this APU is able to adhere with some of AMD’s fastest quad-core desktop processors, while additionally alms discrete-class GPU performance.


The AMD A8-3870K differentiates itself from the A8-3850 it supplants at the top of AMD's A8 APU agency in two allusive ways. First, the A8-3870K has a 100MHz college absence CPU clock, 3GHz (3870K) against 2.9GHz (3850). Second, as the "K" denotes, the A8-3870K is an apart "Black Edition" APU. That agency the dent is apart for added adjustable overclocking. It's not alone the CPU multipliers that are apart though, but the GPU and anamnesis acceleration multipliers too. The antecedent accumulation of "non-K" Llano APUs were all locked, so overclocking was alone accessible via abject alarm manipulation. With the A8 K SKUs, however, overclocking of the CPU, GPU, and Anamnesis blocks is additionally accessible via multiplier adjustment.


Just to acrylic the complete picture, as we've already mentioned, the AMD A8-3870K APU has a absence CPU alarm acceleration of 3.0GHz. Its four x86 cores are anniversary outfitted with 128KB of L1 Accumulation (64KB Instruction, 64KB Data) and 1MB of L2 accumulation per core, but no L3 accumulation is present. Phenom II processors accept agnate L1 configurations, but alone bisected the L2, additional a ample 6MB L3 cache.


However, remember, this is an APU, so the A8-3870K additionally has an chip DX11-class Radeon HD 6550D GPU core. The GPU runs at a absence abundance of 600MHz and has 400 alive shader ALUs abiding in an arrangement of 5 SIMDs.
