Amd a8 4500m apu with radeon hd graphics


The AMD A8-4500M is a mobile quad-core processor based on the Trinity architecture. Officially presented in Q2 2012, it is the direct follower to the Llano A-series of APUs (Accelerated Processing Unit). The processing unit is produced in 32nm SOI and integrates a 1.9 GHz CPU (up to 2.8 GHz w/ Turbo Core) with a fairly fast Radeon HD 7640G GPU alongside a dual-channel memory controller, video de- and encoders and a northbridge.

The CPU cores are based upon a refunctioned Bulldozer architecture, dubbed Piledriver. Although marketed as a quad-core processor, the A8-4500M contains only two modules through 4 integer-cores and also 2 floating-allude cores complete. As an outcome, the CPU is not atrue quad-core processor.When compared to previous Bulldozer cores, AMD has actually managed to enhance upon the ICOMPUTER (instructions per clock) performance of Trinity cores while allowing for greater clock frequencies. However, once compared to its Llano predecessor, the multithreaded performance of Trinity has actually only been slightly improved. The magnified Turbo Core 3.0 function attributes well in speeding up single threaded performance, although it is still not on the very same level as Intel’s Turbo Boost indistinguishable. Regardmuch less, AMD has actually managed to incorporate various other attributes also, such as the AVX expansion (including FMA) and also support for AES encryption.In terms of raw basic performance, the A8-4500M performs similar to the Llano-based A8-3500M. Single-threaded worktons can especially advantage from the new style and also the updated Turbo Core use. If compared to Intels Core-i3-series, the A8-4500M supplies less performance in the majority of instances. Nonetheless, CPU performance from the AMD processor must be enough for all day-to-day worklots prefer Office, Net looking and also even light video modifying or gaming.

The incorporated DirectX 11-compatible Radeon HD 7640G supplies just 256 shader cores of the Trinity chip (7660G: 384) and, thanks to Turbo Core, will run everywhere in between 497 to 686 MHz depending on the present application demand also. On average, the performance of the HD 7640G GPU is comparable to a dedicated Radeon HD 7610M and also is even faster than the HD Graphics 4000 as found in Intel’s Ivy Bridge.

The power consumption of the A8-4500M APU is rated at 35 Watt TDP and is therefore similar to mid-range dual-core Ivy Bridge processors. Consequently, the A8-4500M is best suited for 14-inch notebooks or bigger.
