Intel Atom E3825

The Intel Atom E3825 is a 2-core, 2-thread mobile processor built on the Silvermont architecture and listed under the Bay Trail-I codename. Its database entry records a base clock of 1333.00, no boost clock, a TDP of 6, an Intel BGA 1170 socket, a 22 nm process node, and Intel as the foundry. The part supports DDR3 memory, does not support ECC memory, integrates HD Graphics, and carries the part number SR1RB. It was released on 2013-10-07, is marked Active in production, and has no populated series field.

Benchmark Performance

The benchmark section of this database entry contains no individual benchmark scores. The benchmarks array is empty, and the nearestRivals array is also empty. The average benchmark score is recorded as 0, and the percentile rank versus all CPUs is 50. Because no rival entries exist, there are no deltaPct values to report and no exact percentage comparisons to competitors can be derived from this data set.

The 50th percentile placement is the only comparative statistic available. It places the E3825 at the middle of the database distribution rather than at the top or bottom. This is a positional rank, not a measured performance figure. The 0 average benchmark score should not be read as a literal speed result; it accompanies an empty benchmarks list, so no actual workload scores are present.

Without nearestRivals, any statement in the style of "ahead by a certain percentage" or "behind by a certain percentage" is unsupported. The data simply does not include rival relationships. The only grounded performance observations come from the specification fields: 2 cores, 2 threads, and a 1333.00 base clock. That combination describes a low-frequency, low-concurrency part. The absence of a boost clock removes the possibility of a higher single-thread frequency state. In summary, the benchmark record for this processor is unpopulated, and the 50th percentile rank is the only meaningful comparative data point.

Power and Thermals

The power profile is anchored by a single TDP value: 6. The benchmark database does not include power draw measurements, thermal limits, or cooler specifications. The 6 TDP value defines the thermal envelope for the whole package, including the integrated HD Graphics, though the data set does not break out graphics power separately.

The 22 nm process node is the manufacturing detail most relevant to this low power class. The architecture is Silvermont, and the codename is Bay Trail-I, both of which align with a low-power mobile design point. The market segment is Mobile, reinforcing that the intended environment is compact, thermally constrained, and power-conscious. The lack of a boost clock also means there is no listed higher-frequency state that would create a temporary spike in heat output; the 1333.00 base clock is the only frequency figure in the record.

The cooling tier implied by a 6 TDP envelope is minimal. A large cooling solution is not indicated by the data. A small passive solution or a low-speed active solution would be consistent with this class of part, although the benchmark database does not name a specific cooler. No transistor count or die size is listed, so thermal density at the die level cannot be assessed. Production status is Active, which indicates the processor is still listed as available in the database rather than discontinued.

Who Should Consider It

The E3825 is best suited to workloads that fit within a 2-thread, 1333.00 base clock envelope. With 2 cores and 2 threads, the processor cannot execute more than 2 threads concurrently. The absence of a boost clock means there is no additional frequency headroom for lightly threaded work. This limits the part to low-concurrency tasks where absolute speed is not the primary requirement.

For basic desktop-style work that is not performance-critical, the 2-core layout and integrated HD Graphics could form an acceptable platform, though no benchmark score in the benchmark database confirms this. For content creation workloads that depend on heavy parallel throughput, the data set provides no evidence of multi-threaded strength, and the 2-thread limit is a clear constraint. For gaming, the record lists only HD Graphics, with no gaming benchmark data, and the low-power dual-core design does not suggest high-end graphics performance.

The strongest use case implied by the specifications is an embedded or mobile system where the 6 TDP class and 22 nm process are more important than peak performance. The Mobile market segment reinforces that interpretation. The multiplier is not unlocked, so user-controlled overclocking is not an option. ECC memory is not supported, which further points away from reliability-critical server memory environments. DDR3 is the supported memory type, but the memory bus width and memory bandwidth fields are not listed, so throughput expectations cannot be quantified. The E3825 is therefore best considered for lightweight, low-thread-count, low-power applications.

Single-Thread vs Multi-Thread Behavior

The E3825 has 2 cores and 2 threads, meaning it can only run 2 threads at any given time. This is the central fact for understanding both single-thread and multi-thread behavior. The base clock is 1333.00, and the boost clock field is null, so there is no separate higher frequency for lightly loaded threads. A single-threaded task therefore uses one core at 1333.00, while a 2-thread workload can use both cores at the same 1333.00 base clock.

The cache layout is per core. Each core has 64 KB of L1 cache and 512 KB of L2 cache. This gives each thread access to a dedicated L1/L2 pair. The benchmark database lists no L3 cache and no total L3 figure, so there is no documented shared-cache layer between the cores. With only 2 threads available, any workload that requires more than 2 concurrent threads will exceed the processor's logical resources.

Memory support is DDR3, but the memory bus width and memory bandwidth fields are empty, so the capacity of the data path between memory and cores is not quantified. The lack of a shared cache and the lack of an additional frequency tier mean that the difference between single-thread and multi-thread behavior is defined primarily by thread count. A thread gets a core at 1333.00; 2 threads get both cores at 1333.00; workloads with more than 2 threads cannot be fully serviced. This is a straightforward dual-core, dual-thread design without the frequency flexibility found in parts with a boost clock.
