About Intel Core i5-3439Y

The Intel Core i5-3439Y is a 2-core, 2-thread mobile processor built on Intel’s 22 nm Ivy Bridge architecture. It lands at the 12th percentile among all CPUs, with an average benchmark score of 563. Its 13 W TDP and BGA 1023 package place it firmly in the low-power mobile space, and its nearest rivals all sit within a fraction of a percent in average score.

Single-Thread vs Multi-Thread Behavior

The benchmark split for this chip is defined by its dual-core, dual-thread design. Core count and thread count are both 2, so there are no extra logical threads to tap into for parallel work. That makes the multi-thread performance a direct reflection of two physical cores, no more. In Cinebench R20, the single-core score is 97 and the multi-core score is 687. In Cinebench R23, the single-core score is 231 and the multi-core score is 1638. The R15 multi-core result is 164.

What this means for real workloads is that lightly threaded tasks do not have a high per-core ceiling. The single-core Cinebench scores are low in absolute terms, so the processor will feel most at home when the task is simple or when responsiveness matters more than raw throughput. Multi-threaded workloads can use both cores, but with only two threads the total rendering capacity remains modest. The shared L3 cache is 3 MB, and each core gets 64 KB of L1 and 256 KB of L2. That cache layout is small by later standards, which reinforces the part’s orientation toward basic mobile workloads rather than heavy number crunching.

The listed base clock is 1500.00 and the boost clock is 2.30. That frequency range is low for a Core i5-class part, and the single-thread scores align with that positioning. In practice, the data suggests a processor that can handle bursts of activity but will not maintain high throughput under sustained all-core loads. The multi-thread score is higher in absolute terms than the single-thread score, but both are far down the overall CPU scale. The 12th-percentile ranking is the clearest signal: this is a low-positioned chip by all-CPU standards.

Power and Thermals

The TDP is 13 W, which places the Core i5-3439Y in an ultra-low-power class. This is not a desktop-class thermal envelope; it is a mobile-oriented power budget. The 22 nm process and Intel’s 1,400 million transistors on a 160 mm² die are consistent with that low-power design. A 13 W processor does not imply a high-end cooling solution. Instead, the cooling tier that fits this chip is a modest, compact solution suitable for thin mobile chassis.

The low TDP also means the boost clock of 2.30 is likely sustainable within a small thermal envelope. There is no data in the FACT PACK on sustained power draw or thermal throttling, but the 13 W figure alone indicates that system builders do not need to plan for large heat sinks. The architecture and codename are both Ivy Bridge, and the manufacturing process is 22 nm. That combination points to a mature, power-conscious design rather than a performance-first part.

How It Compares

Intel Core i3-4158U: The i3-4158U has an average benchmark score of 561. The Core i5-3439Y averages 563, giving it a deltaPct of 0.3. That is essentially a tie, with the i5 holding a negligible edge in average score.

AMD Opteron 3320 EE: The Opteron 3320 EE also averages 561. The Core i5-3439Y is 0.4 percent ahead. Again, the difference is tiny and unlikely to separate the two in real workloads.

AMD Athlon II X3 455: The Athlon II X3 455 averages 565, which is slightly higher than the i5-3439Y’s 563. The deltaPct is -0.4, meaning the i5 trails by a very small margin.

AMD PRO A6-8570: The PRO A6-8570 averages 560. The i5-3439Y is 0.6 percent ahead. This is the largest delta among the four rivals, yet it is still a razor-thin advantage.

FAQ

Q: What socket does the Intel Core i5-3439Y use?

A: It uses Intel BGA 1023, a ball-grid array socket used in mobile platforms.

Q: Does this processor support ECC memory?

A: No. The FACT PACK lists ECC memory support as false.

Q: What memory type does it support?

A: It supports DDR3 memory in a dual-channel configuration.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false, so the user cannot adjust the multiplier.

Q: How much cache does it have?

A: It has 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3 cache.

Q: Where does it rank among all CPUs?

A: It sits at the 12th percentile of all CPUs, with an average benchmark score of 563.

Benchmark Performance

The available Cinebench numbers are limited but consistent. In Cinebench R15 multi-core, the score is 164. In Cinebench R20, the single-core score is 97 and the multi-core score is 687. In Cinebench R23, the single-core score is 231 and the multi-core score is 1638. These are the only benchmark scores in the FACT PACK, and they all point in the same direction: this is a low-compute processor.

The average benchmark score of 563 reinforces that conclusion. Compared to its nearest rivals, the deltas are +0.3 percent against the Intel Core i3-4158U, +0.4 percent against the AMD Opteron 3320 EE, -0.4 percent against the AMD Athlon II X3 455, and +0.6 percent against the AMD PRO A6-8570. None of these margins is meaningful. The Core i5-3439Y is effectively a peer of all four rivals, trading places by less than a point in average score.

The multi-thread scores are larger than the single-thread scores, but that is expected for a multi-core Cinebench run because all cores are active. What matters is the absolute position. A Cinebench R23 multi-core score of 1638 is a very modest result for a modern workload, and the single-core score of 231 is even more telling. The 12th-percentile rank among all CPUs is the summary statistic that captures the overall picture.

Who Should Consider It

The Core i5-3439Y is best suited to workloads that do not demand much compute. Its 13 W TDP and 2-core, 2-thread layout make it a fit for compact mobile systems where low power is the priority. For basic office work, the low single-thread scores may be acceptable; tasks like document editing, spreadsheet work, and web browsing do not need sustained multi-core performance.

For content creation, the data is less favorable. The Cinebench R15 multi-core score of 164 and R23 multi-core score of 1638 are low rendering results. Heavy video, 3D, or image-processing workloads that scale across cores would be constrained by the two-thread limit. The single-thread side is also weak, with an R20 single-core score of 97 and R23 single-core score of 231. This is not a processor for demanding creation workflows.

Gaming is harder to assess from the FACT PACK because no integrated graphics data is listed. The CPU-side scores are low, so any gaming scenario would be limited by the processor’s compute position. The 12th-percentile ranking means the i5-3439Y is aimed at productivity-light, power-conscious systems rather than high-performance gaming machines. Users who need a low-power mobile chip for general use and light tasks are the intended audience.

Platform and Compatibility

The Core i5-3439Y is built for the Intel BGA 1023 socket. Because this is a ball-grid array package, it is not a socketed desktop CPU with an easy user-swappable upgrade path. The practical upgrade path is the entire board or system, not the processor alone.

Memory support is DDR3, with a dual-channel bus. ECC memory is not supported. The FACT PACK does not include PCIe data for this processor, so PCIe lane and version information cannot be assessed here. The processor belongs to the Mobile market segment and was released on 2013-01-07. Its part number is SR12Q. The architecture and codename are both Ivy Bridge, and the process node is 22 nm. The die contains 1,400 million transistors on a 160 mm² die. For a mobile platform from this generation, the combination of low TDP, BGA packaging, and dual-channel DDR3 support defines a basic, power-lean compatibility profile.
