AMD’s Fusion Kaveri APU Supports GDDR5 Memory – Report.

Even though Advanced Micro Devices’ Fusion accelerated processing units have featured advanced graphics cores for years, their performance was limited due to insufficient memory bandwidth. With the next-generation high-performance APU code-named Kaveri, AMD will finally unleash its Radeon HD’s potential thanks to a secret weapon, 128-bit GDDR5 memory controller.

AMD Fusion A-series APU code-named Kaveri is projected to feature up to four Steamroller high-performance x86 general-purpose cores as well as GCN architecture-based AMD Radeon HD 7000 graphics engine. However, the most unexpected feature of Kaveri will be its 128-bit memory controller, which will support both DDR3 as well as GDDR5 memory, according to the BrightSideOfNews web-site. The latter memory type should enable very high performance of integrated graphics sub-system for all-in-one and mobile systems. 

Maximum memory bandwidth provided by dual-channel DDR3 memory sub-system at 1866MHz is 29.8GB/s, which should be sufficient for today’s microprocessors, but may be insufficient for powerful graphics adapters. By contrast, an inexpensive 128-bit GDDR5-based memory sub-system with 3400MHz effective clock-speed enables 54.4GB/s of memory bandwidth, or 82% higher compared to DDR3-based subs-system. While this clearly is not enough for a high-end graphics solution, it should be sufficient for modern mainstream graphics adapters that cost $100 - $130 and which truly provide adequate performance in video game.

I just don’t see it for most desktops, you’re too limited with GDDR5 RAM as far as size, that plus it all needs to be soldered down (including the APU) makes it a very inflexible system. Would think that DDR4 is the better way to go or if you’re that hard up for graphics performance by a graphics card, they’re cheap and Intel still has better CPUs.

I just rebuilt my desktop using one of these new AMD chips with the built in video. While I’m not doing gaming, I do use Photoshop and am very impressed with the performance.

the follow on to the Trinity is the Richland ,.being announce next week on March 12,...posted a note on that earlier.

I am trying to decide whether I get that with a new FM2 motherboard and get the Visheria 8250,

I think some of the Tech writers are getting confused between the Kabini and the Kaveri,...

This is great , now the NASD , FINRA and OCC regulators can watch 3d porn in realtime.
