AMD Ryzen 7 3700U vs Intel Core i3-4370T Comparison

The Intel Core i3-4370T and the AMD Ryzen 7 3700U occupy different corners of the processor market, yet their average benchmark scores land within a few points of each other. The i3-4370T is a desktop part from 2015, built on Intel's Haswell architecture, while the 3700U is a mobile chip from 2019 using AMD's Zen+ design. The database records an average benchmark score of 983 for the Intel part and 968 for the AMD part, placing both at the 26th percentile among all CPUs tested. This near-identical overall standing hides a significant gap in multithreaded workloads, where the 3700U outperforms the older Intel chip by a wide margin in the one shared benchmark test.

Where Each One Wins

The AMD Ryzen 7 3700U is the clear winner in multicore-heavy tasks. The head-to-head benchmark data includes only one test: Cinebench R15 multicore. In that test, the 3700U scores 672, while the i3-4370T scores 287. The delta is 57.3% in favor of AMD. This is a decisive margin, driven by the fact that the 3700U has four cores and eight threads, double the core and thread count of the i3-4370T, which has two cores and four threads. For rendering, video encoding, compilation, or any workload that scales across cores, the AMD chip is the superior choice. The 3700U also features a higher boost clock of 4.00 GHz, allowing it to push beyond its base 2.30 GHz under load, while the i3-4370T has no boost clock at all, operating at a fixed 3.30 GHz. The combination of more cores and the ability to burst higher gives the AMD part a structural advantage in multithreaded applications.

The Intel Core i3-4370T does not win any benchmark in the head-to-head comparison, as the wins tally shows zero for the Intel part and one for the AMD part. However, the i3-4370T records a single-core score in Cinebench R20 of 169, and in Cinebench R23 of 403, though no direct single-core comparison against the 3700U is available in the head-to-head data. The 3700U has a single-core score of 139 in Cinebench R15, but the Intel part lacks a corresponding R15 single-core result, so a direct comparison is impossible from the recorded data. What the data does suggest is that the i3-4370T, with its higher base clock and older but simpler architecture, can hold its own in lightly threaded tasks, but the database does not confirm a win for Intel. For a user with a desktop motherboard and a limited power budget (the i3-4370T has a 35W TDP), the Intel part remains a functional option for basic single-threaded workloads, but the 3700U dominates in any task that can use more than two cores.

Head-to-Head Benchmarks

The single recorded head-to-head benchmark is Cinebench R15 multicore. The results are unambiguous. The AMD Ryzen 7 3700U scores 672 points. The Intel Core i3-4370T scores 287 points. The delta, expressed as a percentage, is 57.3 percent in favor of the AMD part. That is not a small gap; the 3700U delivers more than double the score of the i3-4370T. For any workload that scales with core count, this difference is transformative. The 3700U’s 4-core, 8-thread configuration allows it to process two threads per core, whereas the i3-4370T is limited to two cores and four threads. In Cinebench's rendering engine, which uses every available core, the AMD part finishes the task in a fraction of the time.

The remaining benchmarks in the database do not have direct head-to-head matches. The Intel i3-4370T has scores in Cinebench R15 multicore (287), Cinebench R20 multicore (1199), Cinebench R20 singlecore (169), Cinebench R23 multicore (2856), and Cinebench R23 singlecore (403). The AMD 3700U has scores in Cinebench R15 multicore (672), Cinebench R15 singlecore (139), Geekbench multicore (2377), and Geekbench singlecore (682). Since the only overlapping test is the Cinebench R15 multicore, that result stands as the definitive measure between the two. The Intel's singlecore scores in R20 and R23 are not comparable to the AMD's singlecore score in R15, as different rendering versions produce different absolute numbers. The data does record that the i3-4370T has a higher base clock (3.30 vs 2.30), which could give it a per-core advantage in older software, but the 3700U's boost clock of 4.00 GHz is available, so any such advantage is not visible in the recorded head-to-head tests.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core i3-4370T has 2 cores and 4 threads, while the AMD Ryzen 7 3700U has 4 cores and 8 threads. The base clocks are 3.30 GHz for Intel and 2.30 GHz for AMD. The AMD part has a boost clock of 4.00 GHz; the Intel has no boost clock, so it runs at a fixed frequency. Thermal design power (TDP) differs significantly: the i3-4370T uses 35 watts, while the 3700U operates at 15 watts, making the AMD part more efficient per watt for the performance it delivers.

The sockets are incompatible. The Intel uses Intel Socket 1150, a desktop socket, while the AMD uses AMD Socket FP5, which is a mobile socket. This reflects their market segments: the i3-4370T is a desktop processor, and the 3700U is a mobile processor. Memory support also differs. The Intel part supports DDR3 memory, while the AMD part supports DDR4. Both have dual-channel memory buses. The Intel memory bandwidth is recorded as 25.6 GB/s, while the AMD part does not have a memory bandwidth figure in the database. The Intel processor has 16 PCIe lanes at Gen 3, while the AMD part has PCIe Gen 3, but no lane count is recorded for the AMD.

The integrated graphics differ as well. The Intel has Intel HD 4600, and the AMD has Radeon Vega 10. The production status shows the Intel as end-of-life, and the AMD as active. The Intel has a launch MSRP of $138, which can be stated once as the launch MSRP, while the AMD has no launch MSRP recorded. The Intel part has a part number of SR1TB, and the AMD part has a part number of YM370BC4T4MFG. The Intel was released in 2015, and the AMD was released in 2019.

Architecture Differences

The two processors come from different manufacturing nodes and architectures. The Intel Core i3-4370T uses the Haswell architecture, with a codename of Haswell and a generation of "Core i3 (Haswell)". It is built on a 22 nm process at Intel's foundry. The transistor count is 1,400 million, and the die size is 177 mm². The AMD Ryzen 7 3700U uses the Zen+ architecture, with a codename of Picasso, and a generation of "Ryzen 7 (Zen+ (Picasso))". It is manufactured on a 12nm process at GlobalFoundries. The AMD part packs 4,940 million transistors on a die size of 210 mm². The AMD processor is thus built on a more advanced node with more transistors, allowing for a higher core count in the same power envelope.

The cache hierarchies differ in size per core. The Intel has L1 cache of 64 KB per core and L2 cache of 256 KB per core, with a shared L3 cache of 4 MB. The AMD has L1 cache of 96 KB per core and L2 cache of 512 KB per core, also with a shared L3 cache of 4 MB. This means each AMD core has more private cache for its own use. The overall L3 is identical in size, but the AMD part benefits from larger per-core caches, which can reduce memory latency for single-threaded workloads.

The memory support reflects the generation. Intel uses DDR3, which is an older standard, while AMD uses DDR4. This affects the memory bus and bandwidth, though the AMD part does not have a recorded bandwidth figure. The PCIe support is Gen 3 for both, but the Intel part specifies 16 Lanes (CPU only), and the AMD part just says Gen 3. The integrated graphics are also different: Intel HD 4600 versus Radeon Vega 10, with the AMD integrated GPU likely providing more graphics performance, though no benchmark data is recorded for the iGPU.

The architectural differences also explain the power and efficiency gap. The 3700U has a lower TDP of 15W, despite having more cores and a boost clock, because it is built on a smaller 12nm process and uses a mobile-first design. The i3-4370T, with its 22nm process, has a higher TDP of 35W despite being a lower core count and no boost. This makes the AMD part more suitable for laptops, as it consumes less power while delivering higher multithreaded performance. The Intel part, with its desktop socket and DDR3 support, is more suited to a stationary system. The data shows that the AMD part is the more capable processor in multithreaded tasks, while the Intel part is limited to a lower core count and an older platform.

The Intel part's lack of a boost clock is a significant limitation. At 3.30 GHz, it runs at a constant speed, while the AMD can boost up to 4.00 GHz when thermal and power allow. This means that even in single-threaded tasks, the AMD part can exceed its base clock, and its 4-core design can maintain higher sustained performance. The Intel part does have a higher base clock, so for a single thread without any boost, it may be faster than the AMD at its base, but the AMD's ability to boost changes the equation.

The database records no wins for the Intel part in the head-to-head comparison, and the AMD wins the only test. The average benchmark scores (983 for Intel, 968 for AMD) are nearly identical, but this is misleading because the Intel average is based on five Cinebench tests, while the AMD average is based on four tests across two different benchmark suites (Cinebench R15 and Geekbench). The AMD's Geekbench scores are in a different unit base, so the average scores are not directly comparable. The percentile rank is the same at 26th for both, which means they sit in the same overall tier of performance, but the multicore advantage of the AMD is substantial.

For a user choosing between these two, the decision is primarily about platform and workload. If the platform is a desktop motherboard with DDR3 and a 1150 socket, the i3-4370T is the only choice, but it will lag in any multicore task. If the platform is a mobile laptop with the FP5 socket, the 3700U offers better performance per watt and more cores. The data shows no scenario where the Intel wins a head-to-head benchmark, so the 3700U is the recommended pick for any user who values multithreaded performance. The Intel part remains a viable, low-power desktop option for basic tasks, but in the recorded tests, the AMD is the dominant processor.
