Intel Core i3-4350T vs Intel Core i5-4330M Comparison

Head-to-Head Benchmarks

The benchmark data shows a remarkably consistent pattern across the entire Cinebench suite: the Intel Core i5-4330M wins every single test, but by a very narrow margin. In the Cinebench R15 multi-core test, the i5-4330M scores 274 against 271 for the i3-4350T, a delta of 1.1%. That is a meaningful but not decisive advantage. The gap widens slightly in the newer workloads. In Cinebench R20 multi-core, the i5-4330M posts 1145 versus 1130, a 1.3% lead. The same 1.3% delta appears in Cinebench R20 single-core (161 vs 159) and carries through to Cinebench R23, where the i5-4330M scores 2727 multi-core and 385 single-core, against the i3-4350T's 2692 and 380. Across all five recorded head-to-head tests, the i5-4330M wins 5 and the i3-4350T wins 0.

What makes these results interesting is how close the two parts are. A 1.1% to 1.3% lead in every test is the kind of margin that shows up in real-world use as a barely perceptible difference. The i5-4330M does not dominate because of some architectural superiority; it wins because its boost clock of 3.80 GHz gives it a slight edge over the i3-4350T's fixed 3.10 GHz, even though the i3 has a higher base clock. The data suggests that the i5-4330M is consistently, if narrowly, the faster chip in both single-threaded and multi-threaded Cinebench workloads.

Looking at the broader database context, both processors sit at the 25th percentile of all CPUs, meaning they are both firmly in entry-level territory. The i5-4330M has an average benchmark score of 938, while the i3-4350T averages 926. That 12-point gap is small enough that the i5-4330M's nearest rivals include the Intel Core i3-8145U at 941 (0.4% faster) and the Intel Core i7-2715QE at 942 (0.4% faster). The i3-4350T, by comparison, sits near the Intel Core i5-4288U at 927 (0.1% faster) and the Intel Celeron G6900TE at 925 (0.2% slower). Neither chip is breaking any performance records, but the data shows the i5-4330M has a slight statistical edge over its desktop counterpart.

Where Each One Wins

The i5-4330M wins in every benchmark category recorded, but that does not tell the whole story. Its advantages are all in the 1.1% to 1.3% range, which means it wins on raw throughput in both single-core and multi-core Cinebench tests. If you are looking at Cinebench R23 multi-core as a proxy for modern rendering or compilation workloads, the i5-4330M's 2727 score edges out the i3-4350T's 2692. In single-core R23, the 385 vs 380 result favors the i5-4330M for lightly threaded tasks like web browsing, office applications, or older games that rely on one or two threads.

The i3-4350T does not win a single benchmark, but the data does not suggest it is a bad chip. Its 35W TDP is slightly lower than the i5-4330M's 37W, making it marginally more power-efficient on paper. The i3-4350T also has a larger L3 cache at 4 MB shared, compared to the i5-4330M's 3 MB shared, and it supports dual-channel memory with a rated bandwidth of 25.6 GB/s, whereas the i5-4330M's memory bus information is not recorded in the database. For a desktop system where power draw and cache capacity matter more than a 1.3% performance delta, the i3-4350T has qualitative advantages that the benchmark scores alone do not capture.

The real story is that neither chip is suited for heavy workloads. Both sit at the 25th percentile, and their average benchmark scores (938 vs 926) are within 1.3% of each other. The i5-4330M is the faster part, but only just barely, and the i3-4350T makes up ground with a larger cache, a lower TDP, and desktop-oriented features like a 16-lane PCIe Gen 3 connection.

Architecture Differences

Both processors are built on the Haswell architecture, using Intel's 22 nm process node. Both have 1,400 million transistors, and both are dual-core parts with four threads via Hyper-Threading. The similarities end there, however, as the two chips target different market segments with different physical designs.

The i5-4330M is a mobile processor, socketed into Intel Socket G3, with a die size of 118 mm². It has a base clock of 2.80 GHz and a boost clock of 3.80 GHz, meaning it can dynamically increase its frequency when thermal headroom allows. Its integrated graphics are the Intel HD 5000. The i3-4350T is a desktop part, socketed into Intel Socket 1150, with a larger die size of 177 mm². It has a base clock of 3.10 GHz but no boost clock, so it runs at a fixed frequency. Its integrated graphics are the Intel HD 4600.

The cache configurations differ as well. Both have 64 KB of L1 cache per core and 256 KB of L2 cache per core, but the i3-4350T has 4 MB of shared L3 cache versus the i5-4330M's 3 MB. That extra 1 MB of L3 cache could help the i3-4350T in workloads that repeatedly access the same data set, even though the benchmark results show the i5-4330M still wins by a small margin. The i3-4350T also has a dual-channel memory bus with a recorded bandwidth of 25.6 GB/s, while the i5-4330M's memory bus is not specified in the database.

The i3-4350T is marked as end-of-life in production status, while the i5-4330M's production status is not recorded. The i3-4350T has a part number of SR1JUSR1PA and a launch MSRP of $138. The i5-4330M has no recorded launch MSRP. Both chips support DDR3 memory, neither supports ECC, and neither has an unlocked multiplier.

FAQ

Q: Which chip is faster in multi-core workloads?

A: The Intel Core i5-4330M wins every recorded multi-core test. It scores 274 in Cinebench R15, 1145 in R20, and 2727 in R23, against the i3-4350T's 271, 1130, and 2692 respectively. The lead is consistent at 1.1% to 1.3%.

Q: Does the i3-4350T have any performance advantage?

A: The benchmark data shows no wins for the i3-4350T in any recorded test. However, it has a 4 MB shared L3 cache versus 3 MB on the i5-4330M, and a lower 35W TDP versus 37W, which are qualitative advantages not reflected in the Cinebench scores.

Q: Why does the i5-4330M win if the i3-4350T has a higher base clock?

A: The i5-4330M has a boost clock of 3.80 GHz, which allows it to exceed its 2.80 GHz base clock under load. The i3-4350T has no boost clock and runs at a fixed 3.10 GHz. The i5's boost capability gives it the edge in every benchmark.

Q: Are these chips suitable for modern gaming?

A: Both processors sit at the 25th percentile of all CPUs and have average benchmark scores below 940. The data does not include gaming-specific tests, but the low percentile ranking suggests they are not high-performance parts for demanding applications.

Q: What are the integrated graphics on each chip?

A: The i5-4330M uses Intel HD 5000, while the i3-4350T uses Intel HD 4600. Neither is a discrete-class solution, and the database does not include graphics benchmarks for either part.

Q: Which chip has better memory support?

A: The i3-4350T has a dual-channel memory bus with a rated bandwidth of 25.6 GB/s. The i5-4330M's memory bus is not recorded in the database. Both support DDR3 memory, and neither supports ECC.

The Verdict

The data points to a clear but narrow winner. The Intel Core i5-4330M outperforms the Intel Core i3-4350T in every recorded Cinebench test, with deltas ranging from 1.1% to 1.3%. If raw benchmark performance is the only criterion, the i5-4330M is the better chip. Its boost clock of 3.80 GHz gives it a frequency advantage that the i3-4350T cannot match, and that translates into consistent wins across single-core and multi-core workloads.

However, the i3-4350T is not without merit. It has a larger 4 MB L3 cache, a lower 35W TDP, and a dual-channel memory bus with 25.6 GB/s of bandwidth. It also targets a different market segment: desktop, versus the i5-4330M's mobile focus. For a builder assembling a low-power desktop system, the i3-4350T offers a slightly more efficient package with more cache, and its 3.10 GHz fixed clock is respectable for a 35W part. The i5-4330M, meanwhile, belongs in a laptop or a compact mobile system where its boost capability and smaller die size are assets.

The database records both chips at the 25th percentile, and their average benchmark scores are within 1.3% of each other. Neither is a performance powerhouse. The i5-4330M is the faster part, but the i3-4350T is the more feature-complete desktop option, with its larger cache, dual-channel memory support, and lower TDP. Choose the i5-4330M if you need the extra speed and are working in a mobile form factor. Choose the i3-4350T if you are building a desktop and value cache capacity, memory bandwidth, and power efficiency over a marginal benchmark lead.
