The concept is simple: the concurrently-running graphics processors would share the overall “heavy lifting” load, alternatively operating on sequential pixel rows, for example. Why am I sharing this degree of graphics minutia with you? That’s because the intent here was to boost the overall graphics performance of the system to something more modern-ish, by running the two graphics subsystems in an arrangement that AMD at the time called “Hybrid Crossfire” mode (with the “hybrid” qualifier referencing that one of the two GPUs was on the APU, versus being discrete like its peer). The “Bonaire” discrete GPU on the graphics card, conveniently also a member of the Radeon HD 7000 series, offers roughly comparable functionality and performance to the graphics core embedded in the APU. That’s because it embeds not only the processor core but also a graphics core (along with cache and other predictable peripheral stuff), specifically a 512-core variant of the Radeon R7 graphics architecture. They’re the AMD A10-7850K “Kaveri” 3.7 GHz (4 GHz Turbo) 95 W Socket FM2 quad-core APU, along with a Sapphire 100366-2L 2 GByte graphics card based on AMD’s Radeon R7 260X reference design using the “Bonaire” GPU.Ĭareful readers have already noticed that I’ve referred to the A10-7850K as an APU (accelerated processing unit, in AMD vernacular), versus the more conventional CPU. And its backstory is a bit more involved, so I’ve decided to devote an entire post to it.įirst off, let’s discuss the processor and graphics subsystem. The third system I’ll be telling you about today, derived in part from components initially mentioned by me in a post published more than six years ago, is instead intended to be a present for a teenage family member. Recently, I told you about two systems I’d built up for others’ use, which were intended for donation to the clients of Evergreen Christian Outreach’s Shelter Program, along with the organization’s other community services.
