AMD E1-2500

The AMD E1-2500 is a dual-core mobile APU built on the Jaguar architecture and Kabini codename, fabricated on GlobalFoundries' 28 nm process with a 107 mm² die. Released on May 22, 2013, and now end-of-life, this 15 W part targets low-power notebooks and compact systems. With a 1400 MHz base clock, no boost capability, 2 cores and 2 threads, it represents an entry-level compute tier from its era. The integrated Radeon HD 8240 GPU and single-channel DDR3 memory controller round out a platform designed for efficiency over performance.

Platform and Compatibility

The E1-2500 uses the AMD Socket FT3, the socket associated with the Kabini platform. This socket is tied to AMD's low-power APU lineup, and the platform is designated for the mobile segment. The upgrade path is effectively a full board replacement rather than a processor swap, since the socket is not shared with any mainstream desktop platform. The part number EM2500IBJ23HM identifies this specific SKU, and production status is listed as end-of-life, meaning new designs should not rely on ongoing availability.

Memory support is DDR3, accessed through a single-channel controller. The memory bus provides 10.7 GB/s of bandwidth, a modest figure consistent with the low-power positioning. Notably, ECC memory is supported, a feature uncommon in this class and potentially useful for low-cost reliability-oriented deployments. The single-channel configuration, however, limits memory throughput compared to dual-channel designs, which can constrain the integrated graphics and any memory-bandwidth-sensitive workloads.

PCIe connectivity is provided as Gen 2 with 8 lanes available from the CPU. This is a limited allocation — enough for a single discrete GPU or a few expansion devices, but far from the lane counts of desktop platforms. The "CPU only" qualifier in the specification indicates that these 8 lanes are the total available, with no additional lanes routed through a chipset. For a mobile APU, this is adequate for a basic notebook or embedded system.

The cache hierarchy consists of 64 KB of L1 per core and a shared 1 MB L2, with no L3 cache present. The absence of L3 is notable — modern CPUs typically include it, but Jaguar's design philosophy prioritized low power and small die area over deep cache hierarchies. The processor is not multiplier-unlocked, so overclocking is not supported. The 28 nm process yields a die size of 107 mm², and the foundry is GlobalFoundries.

Single-Thread vs Multi-Thread Behavior

The E1-2500 presents a straightforward dual-core, dual-thread configuration — no simultaneous multithreading is present, so the thread count equals the core count at 2. The base clock is fixed at 1400 MHz, and no boost clock is listed, meaning the processor runs at a constant frequency under load. There is no turbo headroom to exploit.

Single-thread performance is therefore governed entirely by the 1400 MHz clock and the Jaguar core's instruction efficiency. Jaguar is a low-power architecture designed for tablets and compact notebooks, not for raw throughput. The per-core L1 cache of 64 KB helps reduce memory stalls, but the lack of L3 and the single-channel memory bandwidth of 10.7 GB/s will limit how quickly data can be fed to the cores. For single-threaded workloads — legacy applications, lightly threaded office tools, or script interpreters — the E1-2500 will feel slow by modern standards, as the clock is low and the architecture is old.

Multi-threaded behavior is similarly constrained. With only 2 threads, the processor cannot exploit modern multi-threaded parallelism beyond a trivial degree. The shared 1 MB L2 cache is small but at least accessible to both cores, which helps when both threads operate on overlapping data. Still, the ceiling is low: two Jaguar cores at 1.4 GHz will struggle with any demanding parallel workload, such as video encoding, compilation, or heavy spreadsheet calculations. The 50th percentile ranking among all CPUs in the database — a median position — reflects this middling status, though it is important to note that the average benchmark score recorded is 0, indicating that no substantive benchmark data has been captured for this part in the database.

Power and Thermals

The TDP is rated at 15 W, placing the E1-2500 in the ultra-low-power class. This is the defining characteristic of the processor: it is engineered to operate within a tight thermal envelope suitable for compact mobile designs. The 28 nm process from GlobalFoundries is the enabling factor, allowing a dual-core APU with integrated graphics to fit within 15 W.

Cooling requirements are minimal. A small heatsink with a low-speed fan would suffice, and the mobile segment designation confirms that this is not a desktop part; it is intended for laptops, mini-PCs, and embedded systems where thermal dissipation is limited. The 107 mm² die size and absence of a boost clock mean that power draw remains steady, with no thermal spikes from turbo behavior. For system integrators, the 15 W TDP simplifies power delivery design — a modest voltage regulator is adequate, and battery life in portable devices benefits from the low draw.

The ECC memory support adds a wrinkle: error-correcting memory typically increases power consumption slightly, but the overall platform power remains dominated by the APU's 15 W envelope. In practice, the thermal solution for this part is trivial compared to mainstream desktop processors, which is precisely the point of the Kabini platform.

Who Should Consider It

The E1-2500 is not a performance part. Its 2 cores, 2 threads, 1400 MHz clock, and integrated Radeon HD 8240 graphics place it firmly at the entry level. The data supports this: the average benchmark score of 0 and the 50th percentile ranking suggest a processor that is unremarkable in every measurable way.

For basic office productivity — word processing, spreadsheets, email, web browsing — the E1-2500 is technically sufficient, though users should expect sluggishness with modern, JavaScript-heavy web pages. The single-channel DDR3 memory at 10.7 GB/s will be a bottleneck for anything memory-intensive. For media consumption, the Radeon HD 8240 can drive video playback, but demanding codecs or high resolutions may strain the GPU.

Gaming is not a realistic use case. The integrated graphics, while present, is not designed for 3D workloads, and the CPU's low clock will bottleneck even light games. Content creation — photo editing, video rendering, software compilation — is firmly out of scope; the 2-thread ceiling and low clock make these tasks painfully slow.

The realistic audience is embedded systems, thin clients, and low-cost portable devices where power efficiency trumps performance. The ECC support is a differentiator that could appeal to small-scale server or NAS applications where data integrity matters more than throughput. For anyone else, the end-of-life status and lack of benchmark data should give pause.

Benchmark Performance

The benchmark data for the E1-2500 is sparse. The average benchmark score is recorded as 0, and the nearestRivals list is empty, meaning no direct comparative scores or percentage deltas are available in the database. This absence of data is itself informative: the processor likely never generated enough benchmark submissions to establish a score baseline, or the submissions were not aggregated.

The percentile ranking of 50 places the E1-2500 at the median of all CPUs tracked in the database. This is a curious figure — a median position implies that half of all processors perform worse and half perform better. However, given the 0 average score, the percentile may reflect the distribution of submissions rather than actual performance. Without rival scores or deltas, it is impossible to quantify how far ahead or behind the E1-2500 sits relative to specific competitors.

What can be said qualitatively is that the specifications — 2 cores at 1400 MHz, no boost, single-channel DDR3, no L3 — paint a clear picture of a low-end part. Compared to typical modern processors with higher core counts, boost clocks, and multi-channel memory, the E1-2500 would lag significantly in both single-threaded and multi-threaded workloads. But the database records no such comparisons, so this remains an inference from the specification sheet rather than a measured result.
