AMD discloses performance of future mobile APUs
AMD yesterday detailed their roadmap of mobile Accelerated Processing Units for this year. The company plans three separate families of processors: "Temash" ultra-low power chips for tablets, "Kabini" APUs for netbooks and ultra-thin notebooks, and "Richland" products for ultra-thin and mainstream notebooks. AMD also revealed some of the upcoming APU models, as well as their performance in graphics and office applications. According to those, new chips will have significantly higher performance than previous generation of mobile products, especially in graphics tasks.
Temash and Kabini chips will be implemented as a System on a Chip (SoC) and will be built on 28nm process. The processors will be branded as A4- and A6-Series, and will have up to 4 CPU cores.
Upcoming "Temash" SoC is an A6-1450. This part has 4 cores, based on "Jaguar" design. The processor is clocked at 1 GHz, that is on a par with currently available Z-60 APU for tablets. AMD hasn't disclosed power consumption of the A6-1450. Having HD 8000 series graphics and twice as many cores, the Temash APU outperforms the Z-60 by large margin:
New "Kabini" accelerated unit is an A6-5200. It has HD 8400 graphics, and supports DDR3-1600 memory. There is no information on the clock speed of this SoC. Judging by the performance improvement, the A6-5200 is very likely a quad-core processor:
Richland mobile microprocessors combine Piledriver CPU core with HD 8000 graphics. The chips are built on 32nm technology, and, depending on features, are branded as A8- or A10-Series. Two SKUs, mentioned in AMD announcement, are A10-5750M and A8-5545M. The former is presumably the top mobile "Richland" model with standard power requirements, possibly 35 Watt. The latter is an ultra-low voltage SKU. Both APUs were benchmarked against "Trinity" A10-4600M flagship quad-core processor, and ULV A8-4555M. The results of 3DMark 11 and PCMark7 benchmarks, as well as performance improvements of new chips, are presented in the table below:
Overall, future A10-5750M and A8-5545M APUs have 20% - 40% better performance in 3DMark 11 test, and we can expect about the same type of gains in other graphics applications, like games. "Richland" CPUs scored only 11% - 12% better than their "Trinity" counterparts in PCMark 7 all-around test. Because this test depends on both CPU and GPU performance, we suspect that the difference between "Richland" and "Trinity" APUs in non-graphics tasks will be smaller than 11%.
Another "Richland" mobile APU is an A6-5350M with HD 8450G GPU. This part was used to measure battery life of a reference notebook design, equipped with 14" display, 4GB of DDR3-1600 RAM, 250GB 5400rpm SATA hard drive, and Li-Ion 6-cell 62.16Whr battery. The system was running under control of Windows 7 Home Premium 64-bit OS, and achieved 13 hours run time in idle or eReader mode.
In the second half of 2013, AMD will introduce a successor to "Richland" family, codenamed "Kaveri". The CPU cores on these APUs will utilize Steamroller architecture, and integrated GPU will be upgraded to Graphics Core Next architecture.
