Intel Core 5 320 vs Intel Core i5-14400F Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core 5 320 and the Intel Core i5-14400F is a study in contrasting priorities. The i5-14400F claims a dominant 14 of the 17 recorded head-to-head tests, while the Core 5 320 manages three wins. The margins, however, tell a more nuanced story than the raw win count.

The largest single gap appears in Cinebench R23 multi-core, where the i5-14400F scores 21645 against the Core 5 320's 6197, a difference of 71.4%. This is the widest delta in the entire dataset and confirms that the desktop part's 10 cores and 16 threads overwhelm the mobile chip's 6 cores and 6 threads in heavily threaded workloads. Cinebench R15 multi-core shows a similar pattern, with the i5-14400F at 2181 versus 1054, a 51.7% advantage. PassMark integer math follows the same trend: 81524 versus 32323, a 60.4% gap.

The i5-14400F also leads in memory-sensitive tasks. PassMark data compression shows 315521 against 148779, a 52.8% lead. Random string sorting goes to the desktop chip by 44.8% (32680 versus 18038). Data encryption is 35.2% faster on the i5-14400F, and extended instructions favor it by 33.5%.

The Core 5 320's three wins are concentrated in specific areas. PassMark single-thread shows 4045 versus 3701, a 9.3% advantage for the mobile chip. The find prime numbers test goes to the Core 5 320 by a substantial 27.9% (110 versus 86). These two wins indicate that the Wildcat Lake architecture, despite its lower core count, has a meaningful per-thread efficiency edge in certain workloads.

The gap narrows considerably in floating-point math, where the i5-14400F leads by 30.8% (61319 versus 42440), a smaller margin than the integer test. Physics simulation favors the desktop part by 19.8% (1523 versus 1221). Cinebench R20 multi-core shows a 39.9% gap, and the same percentage appears in R20 single-core (1283 versus 771).

Average benchmark scores reinforce the overall picture: the i5-14400F posts an average of 32279, while the Core 5 320 averages 18023. The desktop part sits at the 83rd percentile of all CPUs in the database, while the mobile chip ranks at the 72nd percentile. The i5-14400F's nearest rivals, including the AMD Ryzen 7 PRO 8840U and Intel Core i9-11900, cluster within 0.5% of its average score, showing it competes at a higher performance tier. The Core 5 320's closest matches, such as the AMD Ryzen 5 1600 and Intel Core 5 120U, sit within 0.7% of its average, placing it in a lower performance bracket.

Where Each One Wins

The data divides cleanly by workload type. The Intel Core i5-14400F is the clear choice for multi-threaded rendering, content creation, and data processing. Its Cinebench R23 multi-core score of 21645 is more than triple the Core 5 320's 6197, making it the better option for video encoding, 3D rendering, and compilation tasks. PassMark multithread confirms this with 25470 versus 15450, a 39.3% lead. Integer-heavy calculations, compression, and encryption all fall firmly in the i5-14400F's favor.

The Core 5 320 wins in two narrow but notable categories. Its PassMark single-thread score of 4045 beats the i5-14400F's 3701 by 9.3%, which suggests better responsiveness in lightly threaded applications like legacy software or certain game engines that depend on single-core performance. The find prime numbers result, 110 versus 86, is a 27.9% win and indicates the Wildcat Lake core handles this specific mathematical workload far more efficiently.

The mobile chip also has structural advantages that the benchmark scores do not capture. It integrates Intel Xe3 Graphics with 2 Xe cores, while the i5-14400F has no integrated graphics at all. The Core 5 320's 15 W TDP versus the i5-14400F's 65 W TDP means it draws far less power, making it suitable for compact systems where heat and energy are constrained. The i5-14400F requires a discrete GPU, while the Core 5 320 can run a complete system on its integrated graphics alone.

Architecture Differences

The two processors come from fundamentally different design lineages. The Intel Core 5 320 uses the Wildcat Lake architecture built on a 3 nm process, while the Intel Core i5-14400F uses Raptor Lake-R on a 10 nm process. This process gap explains why the mobile chip achieves competitive single-thread performance with far fewer resources.

Core and thread counts differ sharply. The Core 5 320 has 6 cores and 6 threads, with no hyper-threading. The i5-14400F has 10 cores and 16 threads, providing more than double the thread count. The desktop chip's base clock of 2.50 GHz and boost clock of 4.70 GHz are both higher than the mobile chip's 1.50 GHz base and 4.60 GHz boost.

Cache hierarchies reflect the different market positions. The i5-14400F has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The Core 5 320 has 192 KB of L1 cache total, 2.5 MB of L2, and only 6 MB of shared L3. The desktop part's larger cache pool is a major factor in its multi-threaded performance advantage.

Memory support diverges as well. The i5-14400F supports both DDR4 and DDR5 over a dual-channel memory bus, and it includes ECC memory support. The Core 5 320 supports only DDR5 and LPDDR5X over a single-channel bus, with no ECC. The i5-14400F also offers PCIe Gen 5 with 16 CPU lanes, while the Core 5 320 provides PCIe Gen 4 with 6 CPU lanes.

The die size difference is substantial: the i5-14400F measures 215 mm², while the Core 5 320's die size is not recorded. The i5-14400F is a desktop processor on Intel Socket 1700, while the Core 5 320 uses Intel BGA 1516, a mobile socket. Neither chip has an unlocked multiplier. The i5-14400F launched in January 2024 with a launch MSRP of $196, while the Core 5 320 is scheduled for April 2026 with a launch MSRP of $340.

The Verdict

The recorded data points to a clear performance hierarchy. The Intel Core i5-14400F is faster in almost every measurable workload, with particularly large margins in multi-core rendering, integer math, and data compression. Its 83rd percentile ranking, average score of 32279, and 20 MB of L3 cache place it in a higher tier than the Core 5 320, which averages 18023 and sits at the 72nd percentile.

The Intel Core 5 320 makes sense only in specific contexts. Its single-thread PassMark score of 4045 exceeds the i5-14400F by 9.3%, and its find prime numbers result is 27.9% better. Its 3 nm process, integrated Xe3 graphics, and 15 W TDP make it a low-power option for mobile or compact systems. The i5-14400F, with its 65 W TDP, dual-channel memory, ECC support, and PCIe Gen 5, is the more capable all-around processor for desktop workstations.

The data does not support the Core 5 320 as a general-purpose alternative to the i5-14400F. It wins only in single-threaded PassMark and prime number calculation, while losing the other 14 head-to-head tests. The i5-14400F's Cinebench R23 multi-core score of 21645 versus 6197 is a decisive gap that no single-thread advantage can offset.
