AMD A4 Micro-6400T

The AMD A4 Micro-6400T is a 4-core, 4-thread mobile processor from AMD based on the Jaguar architecture, with the codename Mullins. The database lists a 1000.00 base clock, a 1600.00 boost clock, a TDP of 5, and integrated Radeon R3 graphics. It supports DDR3 memory on a single-channel bus, uses AMD Socket FT3, and is classified as end-of-life. The benchmark list is empty, no nearest rivals are recorded, and the only positional value is a 50th-percentile standing against all CPUs.

How It Compares

The database contains no nearest-rival entries for the A4 Micro-6400T. There are no rival names, no rival scores, and no deltaPct values. Because of this, no direct comparison can be made against any specific competing processor. The only positional field is percentileVsAllCpus, which is listed at 50. That places the entry at the midpoint of the database’s CPU distribution, but without populated benchmark scores the percentile cannot be tied to a measured test result. The comparison story is therefore defined by the absence of comparative data rather than by a lead or deficit over a named competitor.

Who Should Consider It

The workload profile starts with four physical cores and four threads. Software that uses four or fewer threads can map directly onto the available execution resources. Single-thread workloads will depend on the 1600.00 boost clock, while more parallel workloads can use all 4 cores at once. The 1000.00 base clock is the sustained point listed in the data, so the processor does not advertise a high sustained frequency for heavy all-core loads.

For gaming, the data lists Radeon R3 integrated graphics as the display solution. No gaming benchmark scores are present, so the database cannot support a specific gaming performance claim. The presence of integrated graphics means a separate GPU is not mandatory in the listed configuration, but there is no measured frame-rate or gaming score to confirm a particular experience level.

For content creation, the processor offers 4 threads and a shared 2 MB L2 cache with no L3 cache. Workloads that scale beyond four threads will run out of logical processors. Memory bandwidth is listed as 10.7 GB/s on a single-channel DDR3 bus, which is a concrete constraint for data-heavy creation tasks. The database provides no creation benchmark scores, so the practical recommendation is limited to what the architecture suggests: modest, thread-limited workloads rather than sustained multi-threaded rendering or large dataset manipulation.

For office-style workloads, the mobile segment and low TDP of 5 point toward light-duty use. The combination of 4 cores, a 1600.00 boost clock, and integrated Radeon R3 graphics covers basic parallel task handling and display output. No office benchmark entries exist in the database, so there is no measured productivity score to cite. Still, the part’s specification set is consistent with lightweight mobile systems rather than high-end workstation platforms.

Single-Thread vs Multi-Thread Behavior

The A4 Micro-6400T has 4 cores and 4 threads, which means the thread count is equal to the core count. There is no indication of extra threads per core. A single-threaded workload can use one core and can ramp toward the 1600.00 boost clock. A multi-threaded workload can engage all 4 cores, but each core handles exactly one thread, so there is no additional parallel headroom beyond the physical core count.

The cache layout helps explain the behavior. Each core has 64 KB of L1 cache, while the 2 MB L2 cache is shared. There is no L3 cache listed, making the shared L2 the last level of cache in the hierarchy. This gives the four cores a common storage area for frequently accessed data. The single-channel memory bus delivers 10.7 GB/s of bandwidth, which is the data transfer limit between the processor and memory. Multi-threaded workloads that require frequent memory access will be limited by that bus width, while single-threaded workloads may benefit more from the 1600.00 boost clock.

The difference between the 1000.00 base clock and the 1600.00 boost clock is the available frequency range. When few cores are active, higher clock operation is possible. When all cores are loaded, the sustained clock is more likely to sit near the 1000.00 base figure, given the listed TDP of 5. In short, the processor is better suited to short bursts of lightly threaded work than to sustained all-core compute.

FAQ

A: It has 4 cores and 4 threads. There is no thread count beyond one thread per core.

Q: What memory does it support?

A: The listed memory support is DDR3. The memory bus is single-channel, memory bandwidth is 10.7 GB/s, and ECC memory is not supported.

Q: Does it include integrated graphics?

A: Yes, the integrated graphics is Radeon R3. No graphics benchmark scores are included in the database.

Q: What socket and PCIe generation does it use?

A: It uses AMD Socket FT3 and PCIe Gen 2. No PCIe lane count is provided.

A: No. Its production status is end-of-life, and the release date is 2014-04-28.

Q: Can the multiplier be adjusted for overclocking?

A: The multiplier unlocked field is false, so the data does not indicate unlocked overclocking support.

Benchmark Performance

The benchmark section of the database is empty. The benchmarks array contains no entries, and the average benchmark score is listed as 0. With no measured scores, there is no benchmark performance to analyze. The nearest-rival list is also empty, so there are no deltaPct values that would allow exact percentage comparisons. No statement such as a percentage lead or deficit over another CPU can be derived from the data.

The only performance-position field is percentileVsAllCpus, which is 50. This is a positional marker, but without underlying benchmark entries it cannot be cross-checked against any individual test. The avgBenchmarkScore of 0 reinforces that the database has no populated performance results for this part. Any performance assessment must therefore come from specification-level data: 4 cores, 4 threads, a 1000.00 base clock, a 1600.00 boost clock, a 5 TDP, a single-channel DDR3 memory bus, 10.7 GB/s memory bandwidth, and a 2 MB shared L2 cache.

Because no exact deltas are present, there are no rival percentages to quote. The processor appears in the database as a specification entry with no measured results. The 50th-percentile value should not be mistaken for a benchmark score; it is the only comparative field available, and it stands without supporting data.

Platform and Compatibility

The platform is based on AMD Socket FT3. The architecture is Jaguar, and the codename is Mullins. The database lists the generation as A4 (Mullins). The processor was built by GlobalFoundries on a 28 nm process, with 930 million transistors and a 107 mm² die size. There is no series label, and no L3 cache is present.

Memory support is DDR3 with a single-channel bus and 10.7 GB/s of bandwidth. ECC memory is not supported. The PCIe interface is Gen 2. Integrated Radeon R3 graphics is included on the package. The market segment is mobile, and the production status is end-of-life. The release date is 2014-04-28, and the part number is AM640TIVJ44JB. The multiplier is not unlocked, according to the multiplierUnlocked field.

The upgrade path is limited by the end-of-life status. The database lists no other processors on this platform, so no socket-compatible upgrade options are documented. Systems built around this part would rely on the mobile platform as originally configured. The absence of L3 cache and the single-channel memory controller are the main architectural constraints for compatibility planning.

Power and Thermals

The listed TDP is 5, which is the only power value in the database entry. That is a very low TDP class, and it aligns with the mobile market segment and the 28 nm GlobalFoundries process. The transistor count is 930 million, and the die size is 107 mm². These physical figures provide context for the power envelope but do not replace a thermal measurement.

Because the TDP is 5, the cooling requirement is light. The database does not specify a cooler, a cooling tier, or a thermal solution, so no specific cooler size can be stated. The low TDP suggests that a modest passive or low-capability active cooler would be enough, but the database does not confirm any particular cooler class. The clock behavior is consistent with that power limit: the 1000.00 base clock is the sustained value, while the 1600.00 boost clock represents the higher single-thread or low-load ceiling. The multiplier unlocked field is false, so there is no overclocking headroom indicated by the data.
