AMD E1-2500

The AMD E1-2500 is a mobile dual-core SoC for low-end subnotebooks, which was presented in mid-2013. In addition to 2 CPU cores with a base clock speed of 1.4 GHz (no turbo), the 28-nanometer chip also integrates a Radeon HD 8240 GPU, a single-channel DDR3L-1333 memory controller as well as the Southbridge with various I/O- ports.

Architecture

Both Kabini (for notebooks) and Temash (tablets and compact subnotebooks) are based on AMD's new Jaguar architecture, which replaces the previous Bobcat models (e.g. the E-350). According to AMD, the performance per clock has been increased by about 15 percent. Furthermore, various modern instruction set extensions such as SSE up to version 4.2, AVX and AES are now supported. The finer 28-nanometer process from TSMC allows lower voltages and/or higher clock rates compared to Bobcat, as well as up to 4 CPU cores (Bobcat: 2 cores).

Performance

Due to the low clock speed of just 1.4 GHz, the performance is quite modest and just slightly above the old E2-1800. For office and multimedia tasks, the E1-2500 has sufficient power; however, it will quickly reach its limits in more demanding applications and games.

Graphics

The SoC integrates a Radeon HD 8240 GPU with 128 shaders, which is based on the GCN architecture. The core is clocked at 400 MHz (no turbo). On average, the HD 8240 places somewhere between the Intel HD Graphics (Ivy Bridge) and HD Graphics 4000. However, the performance is often limited by the CPU. Many recent games (as of 2013) are therefore hardly playable. Only older and less demanding games will run fluently.

Power Consumption

The power consumption of the entire SoC is rated at 15 watts. Thus, the E1-2500 is best suited for 12-inch notebooks or larger.
