AMD Ryzen 7 5705G vs Intel Core Ultra X7 368H Comparison

The Verdict

The AMD Ryzen 7 5705G is a desktop processor built for AM4 motherboards, using the Zen 3 architecture on a 7 nm TSMC process. It delivers 8 cores and 16 threads with a 65 W TDP, making it a straightforward choice for builders who need a capable CPU with integrated Radeon Graphics 512SP. The Intel Core Ultra X7 368H, by contrast, is a mobile processor on Intel's BGA 2540 socket, using Panther Lake architecture on a 3 nm Intel process. It provides 16 cores and 16 threads with a 25 W TDP, which is notably lower than the AMD part despite having twice the core count.

The data shows a clear split. The Intel part sits at the 87th percentile among all CPUs in the database, with an average benchmark score of 40,518. The AMD part currently has no recorded benchmark scores and sits at the 50th percentile, meaning its performance position is unverified in the database. For anyone who needs a mobile processor with strong multi-threaded performance, the Intel Core Ultra X7 368H is the only one of these two with actual benchmark data to support it. For desktop builders who want an AM4-compatible chip with 8 cores, the Ryzen 7 5705G is the only option, but its performance profile is not yet established by recorded measurements.

The Intel chip also supports LPDDR5X memory with 153.6 GB/s bandwidth, while the AMD chip uses DDR4 with 51.2 GB/s. The Intel part features PCIe Gen 5 with 4 lanes, whereas the AMD part has PCIe Gen 3 with 16 lanes. These differences matter for system-level performance, especially in memory-sensitive workloads.

Architecture Differences

The AMD Ryzen 7 5705G is built on Zen 3 architecture with the codename Cezanne, manufactured on a 7 nm process at TSMC. It uses 10,700 million transistors on a 180 mm² die. The Intel Core Ultra X7 368H uses Panther Lake architecture on a 3 nm process at Intel's own foundry. The database does not record transistor count or die size for the Intel part.

Cache organization differs significantly. The AMD chip has 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3. The Intel chip has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The L3 cache difference is relatively small, but the per-core L1 and L2 allocations are substantially larger on the Intel side.

The AMD processor uses AMD Socket AM4 and is part of the 5000 series, with a Ryzen 7 generation designation. The Intel processor uses Intel BGA 2540, is part of Core Ultra Series 3, and carries the Ultra X7 generation label with Panther Lake-H suffix. The AMD part is a desktop component; the Intel part targets mobile systems.

The integrated graphics differ as well. AMD includes Radeon Graphics 512SP, while Intel uses Arc B390. Neither part supports ECC memory. Both use dual-channel memory buses, but the memory types differ: DDR4 for AMD, LPDDR5X for Intel.

The production status for both is listed as Active. The AMD part has a release date of 2025-02-23, while the Intel part has a release date of 2026-01-04. Neither has a recorded launch MSRP.

Specification Differences

The core and thread counts differ: 8 cores and 16 threads for AMD versus 16 cores and 16 threads for Intel. Both have 16 threads, but Intel achieves that with twice as many physical cores.

Base clocks: AMD runs at 3.80 GHz base, Intel at 2.00 GHz base. Boost clocks: AMD reaches 4.60 GHz, Intel reaches 5.00 GHz. The Intel part has a higher top speed but a much lower base clock.

TDP: AMD is 65 W, Intel is 25 W. This is a substantial difference, with Intel drawing less than half the power budget of the AMD part.

Memory support: AMD uses DDR4, Intel uses LPDDR5X. Memory bandwidth: AMD has 51.2 GB/s, Intel has 153.6 GB/s, which is three times higher.

PCIe: AMD provides Gen 3 with 16 lanes (CPU only), Intel provides Gen 5 with 4 lanes (CPU only). The AMD part has more lanes but older generation; Intel has fewer lanes but newer generation.

Process node: AMD uses 7 nm from TSMC, Intel uses 3 nm from Intel. The Intel process is significantly more advanced, which helps explain the lower TDP.

Unlocked multiplier: AMD is unlocked, Intel is locked.

Market segment: AMD is desktop, Intel is mobile.

Socket: AMD Socket AM4 versus Intel BGA 2540.

Part numbers: AMD 100-000001800, Intel SA4R7Q9EJ.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark comparisons between these two processors. The AMD Ryzen 7 5705G has no recorded benchmark scores at all, while the Intel Core Ultra X7 368H has a full set of Cinebench and PassMark results.

For the Intel part, the recorded data shows strong multi-threaded performance. In Cinebench R23 multi-core, it scores 28,221, with a single-core score of 3,984. In Cinebench R20, the multi-core score is 11,852 and single-core is 1,673. In Cinebench R15, multi-core is 2,844 and single-core is 401.

PassMark results for the Intel chip include a multi-thread score of 32,956 and a single-thread score of 4,005. Other PassMark results: data compression 312,927, data encryption 25,228, extended instructions 25,669, find prime numbers 321, floating point math 105,681, integer math 88,083, physics 2,857, and random string sorting 38,093.

The Intel part's average benchmark score is 40,518, placing it at the 87th percentile among all CPUs. Its nearest rivals are the Intel Core 7 253PE with an average score of 40,557 (0.1% faster), the Intel Core 5 223PE with 40,585 (0.2% faster), the AMD Ryzen 9 7940H with 40,431 (0.2% slower), and the Intel Xeon 6507P with 40,426 (0.2% slower). The differences are all within a fraction of a percent, meaning the Ultra X7 368H sits in a tightly packed performance cluster.

Since the AMD Ryzen 7 5705G has no recorded benchmarks, no direct comparison of scores is possible. The database shows zero wins for the AMD part and zero wins for the Intel part in head-to-head matchups.

Where Each One Wins

The Intel Core Ultra X7 368H wins in every measurable category in the database, simply because it has recorded benchmark data and the AMD Ryzen 7 5705G does not. The Intel chip demonstrates strong multi-threaded capability with a Cinebench R23 multi-core score of 28,221 and a PassMark multi-thread score of 32,956. Its single-thread performance is also solid, with a PassMark single-thread score of 4,005 and a Cinebench R23 single-core score of 3,984.

The Intel part also wins on memory bandwidth, offering 153.6 GB/s with LPDDR5X versus 51.2 GB/s with DDR4 for the AMD part. This is a threefold advantage that would affect memory-intensive workloads, though the database does not provide direct measurements of this impact.

The Intel part wins on power efficiency as well, with a 25 W TDP versus 65 W for the AMD part. This makes it suitable for mobile systems where thermal and power budgets are constrained.

The AMD Ryzen 7 5705G wins on core count per thread count efficiency in one sense: it provides 16 threads from just 8 cores, meaning each core handles two threads. The Intel part has 16 cores and 16 threads, so each core handles one thread. For workloads that scale with physical cores, the Intel part has an advantage. For workloads that benefit from simultaneous multi-threading, the AMD part's design may be more efficient per core.

The AMD part also wins on PCIe lane count, with 16 Gen 3 lanes versus 4 Gen 5 lanes for Intel. This could matter for desktop systems with multiple expansion cards, though the newer PCIe generation on the Intel side offers higher per-lane bandwidth.

The AMD part has an unlocked multiplier, which allows overclocking. The Intel part is locked. This gives the AMD processor flexibility for users who want to push clock speeds beyond the stock 4.60 GHz boost, though the database does not record any overclocked results.

In summary, the Intel Core Ultra X7 368H is the only one of the two with verified performance data, and its scores place it near the top of the database. The AMD Ryzen 7 5705G remains an unmeasured quantity, so any claims about its performance relative to the Intel part cannot be supported by the recorded data.
