Intel Atom E660T

The Intel Atom E660T is a 1-core, 2-thread mobile processor built on Intel's 45 nm Tunnel Creek Atom architecture. It runs at a base clock of 1300.00 MHz, has no boost clock listed, and carries a TDP of 3 W. The package is Intel BGA 676, the part number is SLH5L, and the release date is 2010-09-13. The production status is End-of-life, and the market segment is Mobile. In this database, the benchmark array is empty, the average benchmark score is 0, and the percentile versus all CPUs is 50. The nearestRivals list is empty, so the entry has no direct competitive data points from the the benchmark database.

Who Should Consider It

Workload recommendations for the Atom E660T have to be built from a sparse performance record. The processor has 1 core and 2 threads, a 1300.00 MHz base clock, and DDR2 memory support. The average benchmark score is 0, and no entry exists in the benchmarks array. That means any gaming assessment is unsupported by measured scores. A single core with two threads at 1300.00 MHz offers no documented headroom for demanding gaming workloads, and the database records no gaming results that would suggest otherwise. The 50th-percentile position among all CPUs is the only relative ranking, but without a non-zero average benchmark score, it does not function as a performance recommendation.

Content creation is similarly difficult to justify from this data. Creation workloads usually benefit from more compute threads, and the E660T provides only 2 threads, with no boost clock to raise frequency under load. The cache configuration is limited to 64 KB of L1 per core and 512 KB of L2 per core, with no L3 cache listed. There are no creation-oriented benchmark records in the the benchmark database. A processor with this profile is not represented in the data as a creation part, and the absence of any benchmark scores means the database offers no evidence of multi-threaded capability beyond the raw thread count.

Office use is the most plausible conventional category, though it is not proven by scores. The E660T could support lightweight input/output and document-oriented tasks on a DDR2 platform, and its integrated graphics are listed as "On certain motherboards (Chipset feature)", which places display output responsibility on the motherboard chipset rather than on a fixed GPU block inside the processor. Still, the database has no office benchmark entries for this chip. The Mobile market segment and 3 W TDP point toward low-power, compact systems where background workload responsiveness matters less than staying within a very small energy envelope. Buyers should consider the E660T only for such mobile or embedded roles, and they should understand that the measured benchmark record is empty.

Power and Thermals

The E660T's TDP is 3 W. That is an ultra-low-power figure and places the processor in the lowest thermal class in the the benchmark database. There is no boost clock listed, so the 1300.00 MHz base frequency is the only operating clock speed in the record. A 3 W TDP indicates that a corresponding cooling solution can be very modest. The data does not specify a particular cooler, but the thermal requirement implied by 3 W is dramatically lower than for typical desktop or higher-power mobile processors.

The silicon itself is fabricated on Intel's 45 nm process node at Intel's foundry. The die size is 26 mm², and the transistor count is 47 million. These figures reinforce the low-power design: a small, older-node die running at a modest clock speed with no boost state. The cache hierarchy contributes to the light footprint as well: 64 KB of L1 per core and 512 KB of L2 per core, with no L3 cache listed.

Memory support is DDR2, and ECC memory is false. DDR2 carries lower power and bandwidth characteristics than later memory generations, which fits the 3 W envelope. The integrated graphics are not automatically part of every system; they are described as a chipset feature available on certain motherboards. That means the thermal contribution from graphics may vary by motherboard implementation. The multiplier is not unlocked, so there is no overclocking provision in the data. In short, the E660T belongs to a cooling tier best described as minimal, with the 3 W figure as the primary thermal reference.

How It Compares

The nearestRivals array in the the benchmark database is empty. There are no rival product names, no comparative scores, and no deltaPct values. Because of that, this processor cannot be positioned against any specific competitor using the available data. The only relative figure is percentileVsAllCpus, which is 50. That places the Atom E660T at the midpoint of the CPU distribution in the database, but the average benchmark score is 0 and the benchmarks array is empty, so the percentile is not supported by any measured sample.

Without nearest rival entries, there are no rival paragraphs to write. The data simply does not offer a comparison set. If the database later populates nearestRivals with scores and deltaPct values, a direct comparison would become possible. For now, the absence of rivals is itself a significant finding: the E660T has no measurable competitive positioning in this record.

Platform and Compatibility

The Atom E660T uses the Intel BGA 676 socket. Memory support is DDR2, and ECC memory is not supported. No PCIe information is provided in the the benchmark database, so lane counts or revisions cannot be stated. The integrated graphics are present only "On certain motherboards (Chipset feature)", which makes display support dependent on the motherboard's chipset rather than guaranteed by the processor alone.

The architecture is Atom, the codename is Tunnel Creek, and the generation is listed as Atom (Tunnel Creek). The series field is null. The processor was released on 2010-09-13 and is now marked End-of-life. The part number is SLH5L. Because the production status is End-of-life, the data does not indicate an active forward-looking upgrade path. No other processors are listed as compatible in this the benchmark database, so a drop-in upgrade to another CPU on the same socket cannot be identified from the available information.

The platform is therefore defined by its older memory type, mobile segment, and BGA 676 socket. The multiplier is not unlocked, which rules out overclocking as a compatibility consideration. The 45 nm process node, 26 mm² die size, and 47 million transistor count describe the physical package. For a system builder, the relevant facts are straightforward: a Mobile Atom processor for Intel BGA 676 boards, DDR2 memory support, no ECC, no PCIe data, and graphics that depend on the motherboard chipset.
