AMD Unveils Elite A-Series APUs With Enhanced Performance, Improved Efficiency
MojoKid writes "AMD has just announced a new family of Elite A-Series APUs for mobile applications, based on the architecture codenamed 'Richland.' These new APUs build upon last year's 'Trinity' architecture, by improving graphics and compute performance, enhancing power efficiency through the implementation of a new 'Hybrid Boost' mode which leverages on-die thermal sensors, and offering AMD-optimized applications meant to improve the user experience. AMD is unveiling a new visual identity as well, with updated logos and clearer language, in a bid to enhance the brand. At the top of the product stack now is the AMD A10-5750M, a 35 Watt, 3.5GHz quad-core processor with integrated Radeon HD 8650G graphics, 4MB of L2 cache and a DDR3-1866 capable memory interface. The low-end is comprised of dual-cores with Radeon HD 8400G series GPUs and a DDR3-1600 memory interface."
Not exactly, AMD had single-core power boosts since quite some time now. This is a refined version that calculates the boost based on real-time sensor data, instead of using conservative assumptions. So basically: the better you dissipate heat, the faster it goes.
They are both essentially dynamic overclocking, and both rely on thermal data. I'd say they are more alike than dissimilar. I'm not saying it's a bad thing that AMD has done this, but I'd much rather see IPC improvements than brute force attempts to lower the existing performance gap between the two vendors.
Only in single-threaded tasks. You get into multi-threaded and AMD begins to win outright.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
Because AMD unlike Intel (nawadays) makes next gen chips available for previous gen motherboards. So total cost of ownership is substantially lower with AMD than Intel. I got 3x performance boost on a several year old system this way. Because their motherboards are cheaper and use normal RAM (RDRAM debacle, anyone?). Because Intel has tried and failed to screw the enthusiast consumer for decades (except for that celeron 300 -> 450 thing, that rocked). Because their multithreaded performance is better, because their 8 core chips are cheaper, and some of us run an operating system and compute jobs that take full advantage of multiple cores. Because some of us _like_ AMD, and their continued existence means lower CPU prices for everyone.
Maybe that's why.

You've never run a video transcode or compiled anything, have you?
I transcode Fraps recordings and upload them to Youtube, transcode bluray video for my Nexus 7, my MythTV backend often has transcode and commflag jobs queued that could run in parallel with no performance loss if it had more cores. 7-Zip will happily multithread compression tasks across dozens of cores. None of that is particularly exotic.
When you say "real world shit" you're talking about games, right? Be aware that there are things other than World of Warcraft that will tax a CPU, and they aren't imaginary or hypothetical.
