AMD Godavari A10-7870K and A8-7670K ‘Kaveri-Refresh’ APUs Officially Launching Tomorrow
AMD is launching their latest Godavari A10-7870K and A8-7670K APUs tomorrow for the Kaveri-Refresh FM2+ platform. Both new processors are more refined variants of existing Kaveri based flagship parts which include the A10-7850K and A8-7650K that were launched back in January 2014. The new processors feature high core clock speeds and faster graphics chips compared to their predecessors.
FM2+ Finally Gets Godavari - AMD A10-7870K and A8-7670K Launching Tomorrow
The AMD Godavari lineup consists of several chips, most of which are aimed at OEM PCs with the A-8000 Series branding while the consumer desktop lineup is still using the A-7000 series branding scheme. There's no major difference between Kaveri and Godavari lineup which is limited solely to increase in clock speeds for core and graphics chips. AMD has said that the Godavari APUs feature a more power efficient architecture but overall, both chips should perform relatively similar.
The main processor of the lineup, the A10-7870K will launch along side the A8-7670K tomorrow. The specs for the chip can be found below and we will tell you a bit about the performance improvements. As per AMD's official slides, AMD is firstly advertising their latest Radeon series memory showcasing that the chip gets more 1.8x performance boost with 1866 MHz and 2x performance boost with 2400 MHz DRAM modules compared to traditional 1600 MHz memory. On the other hand, we can see some performance benchmarks of A10-7870K in Dirt: Rally which is going to be bundled with the APUs. The game runs pretty good at 40 FPS (1080P Medium settings) and Dual graphics allows additional performance boost of 45 FPS when paired with a Radeon R7 250 discrete graphics cards (1080P, High Settings). There's also sysnthetic benchmark which show 5-10% increases in OpenCL, PCMark 8 and 3DMark benchmarks. AMD is aiming to launch their A10-7870K APU under $150 US.
AMD A10-7870K APU:
The AMD A10-7870K is the flagship APU of the lineup featuring a 4 core and 4 thread design. The chip boasts a clock speed of 3.9 GHz base and 4.1 GHz boost while featuring an unlocked design for overclocking. The chip is featuring the Radeon R7 graphics core based off the Sea Islands GCN architecture that has 512 streaming cores and a clock speed of 867 MHz. The chip will feature 4 MB of L2 cache, 95W TDP and DDR3 memory support of up to 2133 MHz. It will feature a price close to the current generation A10-7850K APU at around $137 US and will likely get better performance and efficiency.
AMD A8-7670K APU:
The AMD A8-7670K APU also features a 4 core and 4 thread design. The chip boasts a clock speed of 3.6 GHz base and 4.0 GHz boost. The clocks can be further boosted with overclocking since the chip is designed with a unlocked multiplier. The chip is featuring the Radeon R7 graphics core based off the Sea Islands GCN architecture that has 512 streaming cores and a clock speed of 867 MHz. The chip will feature 4 MB of L2 cache, 95W TDP and DDR3 memory support of up to 2133 MHz. The price will be around $129 US at launch.
Some additional performance results for the chip were shown by CPUWorld at few days ago with proper benchmarks of the A10-7870K. The chip gets a 20% faster graphics processor thanks to the clock boost. However, when it comes to CPU benchmarks, the chip throtlled down to the lowest power state under heavy loads after 20 seconds which prevented CPUWorld from running proper CPU benchmarks.
AMD A10-7870K CPU-Z Shots (Courtesy of CPU-World):
Wprime 32M benchmark runs only 12 - 13 seconds, and the 7870K processor has enough time to finish the test before the throttling starts. Consequentially, we get accurate wprime 32M numbers. Things change radically when the test takes longer than 20 seconds, as in the case of the 1024M benchmark. Here is the A10-7850K greatly outperforms the A10-7870K, as the latter processor runs half the time at 1.6 GHz due to throttling. This happens even in single-threaded tasks like SuperPi, therefore it is unlikely that the throttling occurs due to CPU overheating. Disabling all low power states and "Thermal throttling" in BIOS does not affect this behavior in any way. We suspect that the new stepping comes with different power management algorithm that gives more power to the GPU, and even more aggressive at throttling down the CPU cores. It may require updated BIOS and/or other software that hopefully will be available before the APU is officially released. At this time we would suggest not to buy the APU unless your board officially supports it. via CPUWorld
It should be noted that Godavari will be the last APU series for the FM2+ platform after which AMD transitions to 2016 and launches their AM4 platform that will support both Zen based FX processors and Excavator based 7th generation APU lineup.
