AMD Ryzen 3 7320U vs Intel Xeon E3-1545M v5 Comparison

Head-to-Head Benchmarks

The benchmark data records four head-to-head comparisons between the Intel Xeon E3-1545M v5 and the AMD Ryzen 3 7320U. The results are split, with each processor claiming victories in different tests. The AMD Ryzen 3 7320U wins three of the four recorded comparisons, while the Intel Xeon E3-1545M v5 takes one, and it is a decisive one.

Starting with Cinebench R15 multicore, the AMD Ryzen 3 7320U scores 790 against the Intel Xeon E3-1545M v5's 654. That is a delta of -17.2% from the Intel part's perspective, meaning the AMD chip is ahead by roughly 17.2% in this older rendering workload. The gap is substantial and shows the AMD processor's efficiency in a multithreaded scenario that does not scale with the Intel chip's higher power envelope.

Cinebench R15 singlecore is an even larger win for the AMD Ryzen 3 7320U. The AMD part scores 162.4, while the Intel Xeon E3-1545M v5 manages only 92. That is a delta of -43.3%, meaning the AMD chip is more than 43% ahead in single-threaded performance on this test. This is a stark difference and points to the architectural advantage of the Zen 2 core design in lightly threaded workloads, despite the Intel part having a higher base clock of 2.90 GHz versus 2.40 GHz.

The picture changes completely in Cinebench R23 multicore. Here the Intel Xeon E3-1545M v5 scores 6497, while the AMD Ryzen 3 7320U scores 4809. The delta is 35.1% in favor of Intel. This is the largest margin in the entire head-to-head set, and it flips the narrative. In a modern, more demanding multi-threaded render, the Intel chip's 45 W TDP and 8 MB of shared L3 cache appear to deliver a significant advantage over the AMD chip's 15 W design and 4 MB of L3.

Finally, Cinebench R23 singlecore returns the advantage to AMD. The Ryzen 3 7320U scores 1095 against the Intel Xeon E3-1545M v5's 917, a delta of -16.3%. While not as dramatic as the R15 singlecore margin, it still confirms that the AMD core architecture holds a consistent single-threaded lead across both generations of the Cinebench test.

The recorded data also includes Cinebench R20 scores outside the head-to-head table. In R20 multicore, the Intel Xeon E3-1545M v5 scores 2728, and in R20 singlecore it scores 385. The AMD Ryzen 3 7320U does not have R20 scores recorded in the database, so a direct comparison there is not possible. However, the R20 numbers for Intel are consistent with the pattern seen in R23: the Xeon part is strong in multicore relative to its own R15 result, while its singlecore R20 score of 385 is modest compared to the AMD part's R23 singlecore result, though these are different test versions.

The average benchmark score in the database places the AMD Ryzen 3 7320U at 1916, while the Intel Xeon E3-1545M v5 sits at 1879. Both processors occupy the 43rd percentile among all CPUs in the database. The AMD part's nearest rivals include the Intel Core i7-6700T at 1918 (-0.1% delta), the Intel Xeon E-2314 at 1911 (+0.3%), the Intel Xeon E3-1575M v5 at 1910 (+0.3%), and the AMD Ryzen 5 PRO 2400GE at 1910 (+0.3%). The Intel Xeon E3-1545M v5's nearest rivals are the Intel Processor U300 at 1881 (-0.1%), the Intel Xeon E3-1558L v5 at 1882 (-0.2%), the Intel Xeon E3-1270L v4 at 1883 (-0.2%), and the Intel Xeon D-1531 at 1885 (-0.3%). These percentile and rival data indicate that both processors sit in a similar performance tier overall, despite their very different design philosophies and benchmark personalities.

The win tally stands at 1 for Intel and 1 for AMD in terms of head-to-head benchmark victories, with AMD taking three wins for AMD and one for Intel. The average scores are close, with AMD slightly higher, but the individual test outcomes show that neither chip is universally faster.

The Verdict

The data does not declare a single overall winner. Instead, it shows two processors with complementary strengths. The AMD Ryzen 3 7320U is the clear choice for single-threaded and lightly threaded workloads. It wins Cinebench R15 singlecore by 43.3%, Cinebench R23 singlecore by 16.3%, and Cinebench R15 multicore by 17.2%. Its boost clock of 4.10 GHz, higher than the Intel part's 3.80 GHz, aligns with these results. The Intel Xeon E3-1545M v5 is the pick for modern multi-threaded rendering, as demonstrated by its 35.1% lead in Cinebench R23 multicore.

For users who prioritize legacy single-core performance or who work in environments where single-threaded speed is the bottleneck, the AMD Ryzen 3 7320U is the better option. For those who run current multi-threaded workloads such as modern video encoding or 3D rendering, the Intel Xeon E3-1545M v5 offers a substantial advantage. The AMD part's 15 W TDP also makes it suitable for thin-and-light mobile devices, while the Intel part's 45 W TDP suggests a heavier, more power-hungry platform.

The average benchmark scores are nearly identical, with AMD at 1916 and Intel at 1879, a difference of less than 2%. Both sit at the 43rd percentile in the database. This means that for a general mix of tasks, the two processors are roughly equivalent. The decision should come down to the specific workload mix. The AMD Ryzen 3 7320U also has a much higher memory bandwidth at 88.0 GB/s compared to the Intel part's 34.1 GB/s, which could benefit memory-intensive applications. On the other hand, the Intel Xeon E3-1545M v5 supports ECC memory, a feature absent from the AMD chip, which may be critical for certain server or workstation use cases.

The Intel Xeon E3-1545M v5 is an end-of-life product with a launch MSRP of $679, while the AMD Ryzen 3 7320U is active and part of the Ryzen 3 7000 series. Production status and release dates differ significantly, with Intel's release in 2016 and AMD's release in 2022. The AMD part's newer process node at 6 nm, manufactured by TSMC, contrasts with Intel's 14 nm process node manufactured by Intel's foundry.

In short, pick the Intel Xeon E3-1545M v5 for maximum multi-threaded performance in current Cinebench R23 workloads, and pick the AMD Ryzen 3 7320U for single-threaded speed and energy efficiency.

Where Each One Wins

The AMD Ryzen 3 7320U wins in all single-threaded tests recorded. In Cinebench R15 singlecore, it outscores the Intel part by 43.3%, and in Cinebench R23 singlecore, it leads by 16.3%. It also wins Cinebench R15 multicore by 17.2%. The AMD chip's higher boost clock of 4.10 GHz compared to 3.80 GHz for the Intel part supports these results. Its memory bandwidth of 88.0 GB/s is more than double the Intel part's 34.1 GB/s, which may help in memory-bound scenarios. The AMD part also has a smaller die size at 100 mm² versus 171 mm² for Intel, and its 6 nm process node is more advanced than Intel's 14 nm node.

The Intel Xeon E3-1545M v5 wins Cinebench R23 multicore by 35.1%. Its score of 6497 versus 4809 for the AMD chip is the single largest margin in the head-to-head data. The Intel part has 8 MB of shared L3 cache versus 4 MB for the AMD part, and a higher base clock of 2.90 GHz versus 2.40 GHz. It also supports ECC memory, which the AMD chip does not. The Intel part's 45 W TDP suggests it can sustain higher power draw for longer periods, which likely contributes to its multicore advantage. In the database, the Intel part's Cinebench R20 multicore score of 2728 and singlecore score of 385 further illustrate its profile, though the AMD part lacks R20 scores for comparison.

The AMD Ryzen 3 7320U has a higher average benchmark score of 1916 against Intel's 1879. Both parts are at the 43rd percentile, but the AMD part's average is slightly higher. The AMD chip's nearest rival in the database is the Intel Core i7-6700T with an average score of 1918, just 0.1% higher. The Intel Xeon E3-1545M v5's nearest rival is the Intel Processor U300 at 1881, just 0.1% higher. These rival data show that both chips are tightly clustered with a set of similar-performing processors.

For use-case planning, the AMD Ryzen 3 7320U is better suited for tasks like office productivity, web browsing, and any application that relies on single-threaded speed. Its 15 W TDP also makes it a better fit for fanless or passively cooled designs or devices where battery life is a priority. The Intel Xeon E3-1545M v5 is better suited for multi-threaded rendering, video encoding, or server-style workloads where the extra power draw is acceptable and ECC memory support is required.
