Architectural Differences
- Core Count: The Ryzen 5 7530U uses a traditional core architecture, whereas the i5 1235U has a hybrid core architecture. This means that the Ryzen has only 6 performance cores, whereas the Intel processor packs in 2 performance cores as well as 8 efficiency cores in its package. This allows both processors to have a total of 12 threads.
- Clock Speeds: The Core i5 has two sets of boost and base frequencies because of its different core architecture. At its lowest, the 1235U has a frequency of 0.9GHz, while it can boost up to 4.4GHz. On the other hand, Ryzen can have a frequency of anywhere from 2.0GHz to 4.5GHz.
- TDP: Both the processors are fairly low-powered, which allows them to make do with a TDP of 15 watts.
- L3 Cache: The Ryzen outclasses the i5 in terms of L3 cache. It has 16 MB, whereas the i5 has a cache of 12 MB.
- Process Size: The Ryzen 5 7530U is based on a more modern processing size of 7nm, whereas the i5 1235U uses a slightly older lithography comprising processing nodes of 10nm.
- Memory: Both processors support up to 64GB of memory, though the Intel processor can accommodate both DDR4 and DDR5, whereas the Ryzen can only make use of DDR4.
Though the Ryzen 5 7530U seems like a processor using AMD’s latest architecture, it uses the fairly dated Zen 3 architecture for its design, as indicated by the second last number in its model name. Because of this, consumers might find this processor to be a better match for a slightly older Intel processor like the 1235U. In comparing the Core i5 1235U vs Ryzen 5 7530U, we will see if this new AMD processor using an older architecture is better than one of Intel’s last-generation processors.
Core i5 1235U Vs Ryzen 5 7530U – Benchmarks
The hardware specifications of these processors paint a picture of them being comparable in terms of performance, which might not translate into real-world performance.
To see if this hypothesis of equivalence holds up in real-world performance, we have rallied up a couple of laptops with each processor to test their performance difference.
The nature of mobile processors means that you are certain to experience a difference in performance from machine to machine, so take the numbers in this section with a grain of salt.
Cinebench R23
- Kicking off our benchmark suit with Cinebench R23, the 1235U outperformed the Ryzen in the single-core test by about 14%. It had a score of 1640 points, whereas the Ryzen had a score of 1439 points.
- The multi-core performance showed us the opposite result, with the Ryzen performing 26% better than the Intel processor, accumulating a score of 8361 points. In contrast, the i5 had a score of around 6601 points. This increase in performance on the Ryzen is due to the higher number of high-performance cores.
Geekbench 6
- Geekbench 6 seemed to favor the newer processor, with around 9% better performance in single-core score. The i5 had a score of 1688 points, whereas the Ryzen had a score of around 1827 points.
- The superiority of the Ryzen translated to the multicore performance, scoring 7% better than the i5. The R5 scored 6016 points, whereas the i5 1235U performed around 5677 points.
Geekbench 5.4
- Curiously enough, the test results were flipped over when we used the older Geekbenh 5.4. The Intel processor had an 8% lead over Ryzen in terms of single-core performance. The i5 1235U had a score of 1546 points, whereas the Ryzen 5 7530U had a score of around 1436 points.
