Intel Core i3-4150T vs Intel Core i3-4370T Comparison

Head-to-Head Benchmarks

The data paints a clear picture: the Intel Core i3-4370T wins every single benchmark in the head-to-head comparison, taking all five tests with a decisive 5-0 sweep. This is not a marginal victory — the margins are remarkably consistent, hovering just under 18% across nearly every workload. In Cinebench R15 multicore, the 4370T scores 287 against the 4150T's 244, a 17.6% advantage. That gap widens slightly in Cinebench R20 multicore, where 1199 versus 1018 yields a 17.8% delta.

The single-core results tell the same story. In Cinebench R20 single-core, the 4370T posts 169 versus 143, a 18.2% lead — the largest margin of any test. Cinebench R23 single-core shows 403 against 342, again a 17.8% gap. The consistency of these deltas is striking; whether the workload is single-threaded or multi-threaded, the 4370T's advantage remains almost perfectly uniform. This suggests the performance difference is systemic rather than workload-specific.

What does this mean in context? The 4370T's average benchmark score is 983, landing it in the 26th percentile of all CPUs. The 4150T averages 975, also in the 26th percentile. Both sit in the same performance tier overall, yet the head-to-head deltas show a meaningful internal gap. The 4370T's nearest rivals include the Intel Xeon X3470 and Intel Core i7-875K, both matching its 983 average score with 0% delta. The 4150T's rivals include the AMD Athlon X4 840 and Intel Core i3-4130, all at 975 with 0% delta. Notably, the 4150T's closest competitors are actually slightly ahead of it — the Intel Core i5-5257U posts 976, a 0.1% edge.

The data implies that while both CPUs occupy the same performance percentile, the 4370T is punching at the top of that tier while the 4150T sits near the bottom. The 4370T's 17.8% lead in R23 multicore translates to real-world responsiveness in threaded applications, but the single-core advantage of 17.8% is arguably more important for everyday desktop use, where most tasks still rely on one or two threads.

Architecture Differences

Both processors share the same fundamental architecture: Haswell, built on Intel's 22 nm process node at the same foundry. Both pack 1,400 million transistors on a 177 mm² die. The core configuration is identical — 2 physical cores with Hyper-Threading, yielding 4 threads. Neither has a boost clock, so the base clock is the maximum sustained frequency. The 4370T runs at 3.30 GHz while the 4150T runs at 2.90 GHz — a 400 MHz difference that largely explains the performance gap.

The cache hierarchy shows a key divergence. Both have 64 KB of L1 per core and 256 KB of L2 per core, but the L3 cache differs: the 4370T carries 4 MB shared, while the 4150T has 3 MB shared. That extra 1 MB of last-level cache, combined with the higher clock, gives the 4370T a structural advantage in workloads that benefit from larger working sets residing in cache.

Memory support also differs in the specification sheets. The 4370T lists DDR3 memory support with dual-channel bus and a memory bandwidth of 25.6 GB/s. The 4150T also supports DDR3 dual-channel, but its memory bandwidth is not specified in the data. The PCIe configuration varies too: the 4370T lists "Gen 3, 16 Lanes (CPU only)" while the 4150T simply lists "Gen 3" without lane details.

Integrated graphics separate the two as well. The 4370T ships with Intel HD 4600, whereas the 4150T has Intel HD 4400. This is a meaningful difference for users relying on the iGPU, as the HD 4600 is a higher-tier integrated solution. The 4370T also has a launch MSRP of $138, while no launch price is recorded for the 4150T.

Both share the same socket (Intel Socket 1150), the same 35 W TDP, and the same generation designation. Neither has an unlocked multiplier. The 4370T was released on 2015-03-29 and is marked end-of-life, while the 4150T's release date is 2014-04-30 with no production status given. The 4370T has a part number (SR1TB), while the 4150T's is not recorded.

The specification table highlights the key differentiators: clock speed, L3 capacity, memory bandwidth, PCIe lane details, and integrated graphics tier. All other specifications — cores, threads, TDP, socket, architecture, process node, foundry, transistor count, die size, L1/L2 cache, memory type, bus, ECC support, market segment, and multiplier lock — are identical between the two.

The 400 MHz base clock difference is the most significant single specification change. Combined with the 33% larger L3 cache (4 MB vs 3 MB), the 4370T has two structural advantages over the 4150T. The memory bandwidth specification of 25.6 GB/s on the 4370T suggests a fully configured dual-channel DDR3 setup, while the 4150T's lack of a listed figure may indicate a different memory configuration or simply incomplete data.

Where Each One Wins

The 4370T wins in every benchmark category measured. It is superior in multi-threaded rendering workloads, as shown by its 17.6-17.8% lead across all three Cinebench multicore tests. It is equally superior in single-threaded tasks, matching that 17.8-18.2% advantage in the single-core tests. There is no benchmark in the data where the 4150T comes out ahead.

For users running CPU-bound applications — video encoding, 3D rendering, software compilation, or scientific computing — the 4370T's consistent ~18% advantage translates directly to shorter completion times. The higher base clock of 3.30 GHz means every single-threaded task, from spreadsheet recalculation to web browsing to legacy software, will respond faster. The larger L3 cache may also help in workloads with moderate working sets that fit within 4 MB but not 3 MB.

The 4150T's position is more nuanced. Its 975 average benchmark score places it alongside the AMD Athlon X4 840 and Core i3-4130, making it competitive within its immediate peer group. For users who already own a 4150T, the data shows there is no workload where it outperforms the 4370T. However, for someone building a new system today, the 4150T's lower clock and smaller cache mean it will lag behind the 4370T in every measurable scenario.

The integrated graphics difference adds another dimension. The 4370T's HD 4600 provides a higher tier of iGPU performance compared to the 4150T's HD 4400, which matters for light gaming, hardware-accelerated video playback, or systems without a discrete GPU. The 4370T also includes full 16 PCIe Gen 3 lanes from the CPU, while the 4150T's PCIe specification is less detailed.

The Verdict

The data is unambiguous: the Intel Core i3-4370T is the superior processor by every metric measured. It wins all five head-to-head benchmarks, with deltas between 17.6% and 18.2%. The 4370T's higher base clock (3.30 GHz vs 2.90 GHz) and larger L3 cache (4 MB vs 3 MB) provide the structural basis for this advantage. The integrated graphics upgrade from HD 4400 to HD 4600 further widens the gap in systems relying on the iGPU.

Users who need maximum performance from a 35 W TDP Haswell dual-core should choose the 4370T. Its benchmark scores — 287 in R15, 1199 in R20, 2856 in R23 — represent the top of its class, matching the Intel Xeon X3470 and Core i7-875K in average score. The launch MSRP of $138 positions it as a premium option within its segment.

The 4150T remains a functional processor, but the data offers no scenario where it is the better choice. Its average score of 975 trails the 4370T's 983, and its closest rivals include the AMD Athlon X4 840 and A10-7870K — competitors that match it exactly at 0% delta. The 4150T's single advantage is its earlier release date (2014-04-30 vs 2015-03-29), which is irrelevant for current purchasing decisions.

For a new build, the 4370T is the clear pick. For an upgrade path from an existing 4150T system, the 4370T offers a measurable ~18% improvement across all workloads — a substantial jump for a same-socket, same-TDP swap. The data does not support any scenario where the 4150T wins, making the verdict straightforward: choose the 4370T unless the 4150T is available at a significantly lower price, which the data does not address.
