Intel Core 7 350

Intel Core 7 350 is a mobile processor built on Intel’s 3 nm process node under the Wildcat Lake codename. It features 6 cores and 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The chip carries a TDP of 15 watts and is designed for the Intel BGA 1516 socket, placing it firmly in the low-power mobile segment. Benchmark data places this processor at the 71st percentile among all CPUs tested, with an average benchmark score of 17779.

Benchmark Performance

The Core 7 350’s average benchmark score of 17779 sits within a tight cluster of similarly performing rivals. The nearest comparison is the Intel Core 5 221TE, which averages 17860, a delta of -0.5% — meaning the Core 7 350 trails by roughly half a percent. Against the AMD EPYC 9374F, the Core 7 350 comes out ahead by 0.5%, with the EPYC scoring 17693. The AMD Ryzen 5 3600XT averages 17891, which is 0.6% higher than the Core 7 350, and the Intel Core 5 120U averages 17898, a 0.7% advantage. These deltas are all within a single percentage point, indicating that the Core 7 350 performs essentially on par with all four rivals in overall average score, with no meaningful winner or loser in aggregate.

Looking at specific Cinebench workloads, the multicore results show a clear picture. In Cinebench R15 multicore, the Core 7 350 scores 1220 points. Cinebench R20 multicore shows 5373 points, and Cinebench R23 multicore reaches 8030 points. These numbers are not directly comparable across Cinebench versions because each workload scales differently, but the progression from R15 to R23 reflects the expected increase in scoring for newer versions. The multicore scores suggest a processor that can handle moderately threaded workloads — 6 cores and 6 threads — without hyper-threading, so the raw throughput is limited by the physical core count.

Single-core performance is where the Core 7 350 shows its strength. Cinebench R15 single-core scores 292, R20 single-core scores 758, and R23 single-core scores 2046. These are strong results for a 15-watt mobile part, indicating that the 4.80 GHz boost clock is effective in lightly threaded scenarios. The single-core scores are particularly notable when compared to the multicore scores — the ratio between them shows that the chip does not scale linearly with additional cores, which is typical for a design with only 6 threads.

PassMark results reinforce this analysis. The PassMark single-thread score is 4100, while the multithread score is 15170. The multithread score is roughly 3.7 times the single-thread score, which is close to the theoretical maximum for 6 cores without SMT (which would be 6x if scaling were perfect). The data shows real-world scaling is lower due to thermal and power constraints typical of a 15-watt TDP part.

For specialized workloads, PassMark sub-scores provide insight. Data compression scores 143123, which is a strong result for a low-power chip. Data encryption scores 10933, and extended instructions score 12045. Floating point math reaches 42809, while integer math scores 33734. Find prime numbers is notably low at 107, which indicates that the chip is not optimized for integer-heavy prime-number calculations. Random string sorting scores 17238, and physics scores 1173. These sub-scores show a processor that excels at compression and floating-point tasks but struggles with specific integer patterns.

Single-Thread vs Multi-Thread Behavior

The Core 7 350’s boost clock of 4.80 GHz is the primary driver of its single-thread performance. With a base clock of 1.50 GHz, the chip relies heavily on boosting to reach competitive scores. The Cinebench R23 single-core score of 2046 is respectable for a mobile part, and the PassMark single-thread score of 4100 confirms this. For workloads like web browsing, office productivity, or legacy applications that rely on one or two threads, the Core 7 350 will perform well above its low base clock might suggest.

Multi-thread behavior is constrained by the 6-core, 6-thread configuration. Without SMT, each core handles exactly one thread, which simplifies scheduling but limits throughput compared to processors with simultaneous multithreading. The Cinebench R23 multicore score of 8030 is roughly 3.9 times the single-core score of 2046, which is below the 6x ideal. This gap is expected due to power limits — at 15 watts TDP, the chip cannot sustain full boost clocks on all cores simultaneously. The PassMark multithread score of 15170 versus single-thread 4100 shows a similar ratio of about 3.7x.

For real workloads, this means the Core 7 350 is best suited for tasks that are lightly threaded or that alternate between bursts of single-thread and modest multi-thread activity. Video conferencing, document editing, and casual content consumption will feel responsive due to the high boost clock. Compiling code or rendering 3D scenes, which scale well with many threads, will be limited by the 6-thread ceiling. The PassMark data compression score of 143123 indicates that compression tasks, which often use multiple threads but not extreme counts, benefit from the available cores. However, the find prime numbers score of 107 shows that certain algorithmic workloads do not translate well to this architecture.

Power and Thermals

The Core 7 350 has a TDP of 15 watts, which classifies it as a low-power mobile processor. This TDP figure is the thermal design power, meaning the cooling solution must dissipate at least 15 watts under sustained load. For a laptop or compact mobile device, this allows for a thin and light chassis with a passive or small active cooling solution. The 3 nm process node contributes to this efficiency — smaller transistors generally reduce power draw for the same performance level.

The 15-watt TDP implies that a capable air cooler, such as a small heat pipe assembly or a low-profile fan, is sufficient. There is no need for liquid cooling or oversized heatsinks. The boost clock of 4.80 GHz can be sustained in short bursts, but under all-core load, the chip will likely reduce clocks to stay within the 15-watt envelope. This is consistent with the multi-thread scaling observed in the benchmarks — the multicore scores are lower than what a 6-core chip with unlimited power might achieve.

Thermal management is critical for sustained performance. The data shows that in single-thread workloads, the chip can reach high clocks, but in multi-thread workloads, power limits cap performance. For users, this means the Core 7 350 will run cool and quiet during typical office or web use, and only under heavy multi-threaded loads will the cooling solution be stressed. The integrated Intel Xe3 Graphics (2 Xe) also draws from the same 15-watt budget, so gaming or GPU-intensive tasks will further limit CPU boost clocks.

Who Should Consider It

The Core 7 350 is a fit for users who prioritize single-thread responsiveness and power efficiency over raw multi-core throughput. For gaming, the integrated Intel Xe3 Graphics (2 Xe) provides basic rendering capabilities, but the 15-watt TDP and lack of discrete GPU headroom mean that demanding AAA titles will be limited. The high single-thread score of 2046 in Cinebench R23 suggests that older or less demanding games that rely on one or two cores will run smoothly. However, modern games that scale across many threads will be bottlenecked by the 6-thread configuration.

For content creation, the Core 7 350 is a mixed proposition. Photo editing in applications like Adobe Photoshop, which often uses single-threaded filters, will benefit from the 4.80 GHz boost clock. Video editing, however, especially export or rendering tasks, will be slower due to the multicore limits — the Cinebench R23 multicore score of 8030 is modest for such workloads. The PassMark floating point math score of 42809 indicates decent performance for scientific or engineering calculations that use FPU instructions.

Office productivity is where the Core 7 350 shines. Spreadsheet manipulation, word processing, and email clients are largely single-threaded, and the 4100 PassMark single-thread score ensures snappy interaction. Data compression tasks score 143123, which is strong, so archiving files or working with compressed datasets will be efficient. The low TDP also means longer battery life in a laptop, making it ideal for business travelers who need all-day endurance without heavy computational demands.

Platform and Compatibility

The Core 7 350 uses the Intel BGA 1516 socket, which is a ball-grid array design soldered directly to the motherboard. This means the processor is not upgradeable or replaceable — it is permanently attached. The platform supports DDR5 and LPDDR5X memory, but only in a single-channel configuration. This is a notable limitation, as dual-channel memory typically provides higher bandwidth. The memory bandwidth is rated at 59.7 GB/s, which is sufficient for the 6-core design but may bottleneck memory-intensive tasks like integrated graphics.

PCIe support is Gen 4 with 6 lanes (CPU only). This allows for a single NVMe SSD or a modest discrete GPU, but the limited lane count restricts expansion options. The integrated graphics, Intel Xe3 Graphics with 2 Xe cores, share the memory bandwidth and are suitable for display output and light acceleration but not for high-end gaming or compute.

The upgrade path is essentially nonexistent because of the BGA socket. Users cannot swap the CPU for a higher-tier model; the entire motherboard must be replaced. Memory is also fixed in terms of channel count, though capacity can vary. The platform supports ECC memory? No, ECC is not supported, which rules out workstation or server use cases that require error correction. The single-channel memory bus is a significant compromise for a processor with a launch MSRP of $469, as competitors in this price range often offer dual-channel support.

How It Compares

Intel Core 5 221TE: The Core 7 350 trails the Core 5 221TE by 0.5% in average score (17779 vs 17860). This is a negligible difference, meaning the two chips are effectively interchangeable in performance. The Core 7 350’s higher boost clock likely offsets the Core 5 221TE’s advantages in other areas, but the data shows no clear winner.

AMD EPYC 9374F: The Core 7 350 leads the EPYC 9374F by 0.5% (17779 vs 17693). This is surprising given the EPYC’s server-class positioning, but the benchmark average is what it is. The Core 7 350’s single-thread strength may be the deciding factor, as server workloads often favor multi-thread performance where the EPYC should theoretically excel. The 0.5% delta is within noise, so real-world differences would be imperceptible.

AMD Ryzen 5 3600XT: The Ryzen 5 3600XT outperforms the Core 7 350 by 0.6% (17891 vs 17779). The Ryzen chip is a desktop part with a higher TDP, so its slight edge in average score is expected. However, the Core 7 350 matches it closely while consuming far less power, which confirms the efficiency of the 3 nm process. For mobile users, the Core 7 350 offers comparable performance in a much lower power envelope.

Intel Core 5 120U: The Core 5 120U is 0.7% ahead (17898 vs 17779). Both are low-power mobile parts, so this comparison is the most relevant. The Core 7 350’s slightly lower score suggests that the Core 5 120U has a marginal advantage in aggregate, but the Core 7 350’s 4.80 GHz boost clock may give it a lead in single-thread tasks. The 0.7% delta is too small to influence purchasing decisions.

Architecture and Design

The Core 7 350 is built on Intel’s 3 nm process node, fabricated at Intel’s own foundry. This is a leading-edge node that enables high transistor density and energy efficiency, which is critical for a 15-watt TDP. The codename is Wildcat Lake, and the generation is listed as Core 5 (Wildcat Lake), indicating a unified design family. The core layout consists of 6 physical cores with 6 threads — there is no hyper-threading enabled, so each core handles one thread.

The cache hierarchy is structured as L1 at 192 KB per core, L2 at 2.5 MB per core, and L3 at 6 MB shared across all cores. This gives a total of 1.5 MB of L1 (6 × 192 KB) and 15 MB of L2 (6 × 2.5 MB) before the shared L3. The L2-per-core design is generous, which helps with single-thread performance by keeping frequently accessed data close to the core. The 6 MB shared L3 is modest for a modern processor, but the low core count means each core gets an effective 1 MB of L3 when fully utilized.

Memory support includes DDR5 and LPDDR5X, but only in single-channel mode. This is a significant architectural choice, as dual-channel memory is standard in most processors. The memory bandwidth of 59.7 GB/s is achievable with a single channel of high-speed DDR5 or LPDDR5X, but it limits peak bandwidth. The integrated graphics, Intel Xe3 Graphics with 2 Xe cores, relies on this memory bandwidth, so gaming performance will be constrained.

The process node, codename, and cache design all point to a processor optimized for efficiency and single-thread speed rather than multi-thread throughput. The lack of SMT and the single-channel memory bus are deliberate trade-offs to keep power low. The 6 MB L3, while small, is sufficient for the 6-core design. The chip is not multiplier-unlocked, meaning overclocking is not possible, which is typical for mobile parts. The part number is SAE3F, and the production status is active, with a release date of 2026-04-15.
