E-300 Details

The AMD E-300, launched in August 2011, stands as a relic of early mobile computing, built on the 65 nm Zacate architecture and designed for low-power mobile systems. With a single core and a base clock of 2000 MHz, the processor operates under a 31 W TDP, making it suitable for compact, energy-efficient devices. Despite its age, the E-300 retains a modest presence in benchmark rankings, particularly due to its integrated Radeon HD 6310 graphics, which was a notable feature for its time. As of March 2026, it is among the least competitive processors in modern performance benchmarks, with an overall score of 3835, placing it at #2000 of 2060. Its single-core performance of 3578 and multicore score of 4221 reflect its limitations in today’s computing landscape, where even budget processors far exceed its capabilities.

The E-300 operates on a single-channel DDR3L 1066 memory interface with a maximum capacity of 8 GB and a bandwidth of 21.3 GB/s. It features 61 KiB of L1 cache and 488 KiB of L2 cache, distributed across its single core. The processor is packaged in a PPGA478 socket and supports a range of x86-64 extensions, including SSE4.1, SSE4.2, AVX2, AES-NI, and AMD-V, enabling basic virtualization and encryption capabilities. While it lacks simultaneous multithreading and has a locked multiplier, it includes technologies such as EIST and HT, contributing to power efficiency. The integrated Radeon HD 6310 GPU runs at a base frequency of 313 MHz, with a burst frequency of 756 MHz, supporting up to two displays and providing basic graphics performance for lightweight tasks.

In comparison to its contemporaries, the E-300 is outperformed by nearly every other processor in the benchmark data. It ranks below a wide range of Atom, Celeron, and Sempron processors, even those from the same era. While its multicore score of 4221 is slightly higher than the C-70 and Atom 330, it trails behind nearly all modern and even many mid-tier mobile processors. Its single-core performance, at 3578, places it behind most current low-power Intel Atom and Pentium models, highlighting its outdated processing power. In the broader context of top-tier processors, the E-300 is over 2000 positions behind leaders like the Ryzen Threadripper PRO 9995WX, which scores over 9000 in overall performance.

Despite its obsolescence, the E-300 remains a testament to AMD’s early efforts in integrating graphics and compute in a single chip for mobile platforms. Its low power consumption and compact design made it viable for netbooks and entry-level laptops during its peak. However, its single-core architecture and limited cache hierarchy render it ineffective for multitasking, content creation, or gaming by today’s standards. For users requiring basic functionality—such as web browsing, document editing, or media playback on older hardware—the E-300 may still suffice, but it offers no competitive advantage in any modern computing scenario. As of 2026, it is best suited for legacy systems or educational demonstrations of early mobile processor design.
