Core i5 1235U Vs Ryzen 5 7530U [Benchmarks 2024]

This comparison between the Core i5 1235U and the Ryzen 5 7530U will test their performance difference in a variety of synthetic and productivity benchmarks whilst also talking about their power consumption and architectural differences.

Though the Ryzen 5 7530U seems like a processor using AMD’s latest architecture, it actually 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.

Architectural Differences

  1. 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.
  2. 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.
  3. TDP: Both the processors are fairly low-powered, which allows them to make do with a TDP of 15 watts.
  4. L3 Cache: The Ryzen outclasses the i5 in terms of L3 cache. It has 16MB, whereas the i5 has a cache of 12MB.
  5. 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.
  6. 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.

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

Frequently Asked Questions

How does Ryzen mobile’s new naming scheme work?

AMD has introduced a confusing naming scheme with its 7000 series of mobile processors. The first number in the model number represents the year, the second represents the model segment (Ryzen 3/5/7/9), and the third represents the architecture.

What does the U at the end of the model name of both these processors mean?

The U at the end of Ryzen 5 7530U and Core i5 1235U means that both these processors are Ultra-low powered.

Why is the multicore performance of the 7530U higher when it has a lower core count?

Though the i5 has a higher number of cores in its architecture, most are weak efficiency cores instead of powerful performance cores.
