For the first time AMD has officially introduced APU Carrizo Carrizo-L in November last year. Then the company again officially unveiled the new hybrid processors for notebooks.
But first let us recall that line of new processors, including no formal desktop models (they may appear only in nettops and monoblocks) is represented by a series of Carrizo-L (core Puma +) and a series of Carrizo (core Excavator). In the first case, at first, will be released 15-watt APU models, in the second - 35 watts. But some other APU became the first single chip assemblies AMD. Now Southbridge with all interfaces moved into the processor. Also, through the use of video core GCN 3.0, the new APU now support the full version of HSA 1.0 (heterogeneous or mixed computing).
Model APU FX-8800P Excavator carries four cores and 8 GPU cores configured with their 512 stream processors. Crystal processor occupies an area of 244.62 square meters. mm. Crystal Kaveri, for comparison, has an area of 245 square meters. mm, but Kaveri contains 2.41 billion transistors. and Carrizo - 3,1 Bln. transistors. At the same time, both generations of processors are manufactured using 28-nm process technology.
Due to architectural improvements, including a doubling of L1 cache volume twice - up to 32 kilobytes, the number of instructions executed per clock cycle from generation APU Carrizo increased by 5-15% over APU Kaveri generation. This and other improvements allow the company to talk about AMD significantly better energy efficiency innovations. For example, when playing video quality 1080 p laptop at APU FX-8800P (Carrizo) worked 11.2 hours, while the laptop is on battery APU Kaveri with a similar capacity spent only 5.3 hours. In mixed mode, the laptop for Carrizo worked 10.2 hours and a laptop on the Kaveri - 7,1 hours.
As for performance, the laptop on the APU A10-8700P (Carrizo) in the benchmark 3DMark FireStrike scored 1100 points and a laptop on the processor Intel Core i5-5200U only 780 points. AMD solution turned out to be productive by 41%. Related Products :
