Articles & Reviews
The launch of Socket AM3+ processors with Piledriver microarchitecture inspired many AMD fans. However, until recently we only based our opinion on the results obtained from the top model in the new AMD FX family. Today we are going to make up for this omission and carry out a detailed performance analysis of all Vishera processors with eight, six and four cores.
Piledriver microarchitecture, a refreshed Bulldozer, has finally reached the flagship AMD FX processors. Will it make the Socket AM3+ platform more appealing than LGA 1155? Quite possible, because the new AMD microarchitecture wasn’t the only trick they had up their sleeve.
Trinity demonstrated some very inspiring performance in graphics tests last week. However, AMD’s traditional weakness is its x86 cores. Let’s see if the company engineers managed to resolve this problem in the new Piledriver microarchitecture that found its way into promising hybrid processors.
New hybrid AMD Trinity processors for desktop systems haven’t been officially launched yet. However, we prepared a detailed review of their graphics omponent.
We will talk about the mainstream and entry-level AMD FX CPU modifications based on Bulldozer microarchitecture and featuring eight-, six- and four-core design.

AMD Bulldozer
Abstract
AMD Bulldozer is the codename for the next generation microarchitecture of AMD’s high-performance processors. This microarchitecture should replace K8/K10 and is developed from scratch.
Bulldozer microarchitecture implies radically new internal structure of the multi-core processors, where pairs of cores form individual modules. Each dual-core module has a single floating-point co-processor shared between the two cores and a shared L2 cache. The modules within the same processor share an 8 MB L3 cache and a memory controller with DDR3-1866 support.
A dual-core module contains up to 2 MB of L2 cache memory and two 128-bit symmetrical floating-point units that may be paired up for 256-bit instructions processing. Each of the two integer cores in the module has two ALU and two AGU, thus enabling each core to perform up to 4 operations per clock cycle. The modules also have shared prefetch and decoding units. This processor architecture allows each module to process two computational threads at the same time, within a semiconductor die of a smaller size.
All Bulldozer processors support contemporary instruction sets including SSE4.1, SSE4.2, AES and AVX.
Each module has 213 million transistors and is 30.9 sq.mm big.
The first processors with Bulldozer microarchitecture will be manufactured using 32 nm SOI process by GlobalFoundries and will be available in three modifications: 16-core server Interlagos for Socket G34 systems, 4-8-core server Valencia for Socket C32 systems and 4-8-core desktop Zambezi for Socket AM3+ systems.
