AMD Ryzen 5 7535U vs Intel Core i7-1270P Comparison

The AMD Ryzen 5 7535U and Intel Core i7-1270P are both 28 W mobile processors aimed at thin-and-light laptops, but benchmark data reveals two distinctly different performance profiles. The Intel chip wins 9 of the 15 head-to-head comparisons, while the AMD chip takes 6, yet the margins tell a more nuanced story than the raw win count suggests. Intel dominates heavily in multi-threaded and floating-point workloads, while AMD counters with significant victories in data compression, encryption, and extended instruction throughput.

Head-to-Head Benchmarks

The largest single gap between the two processors appears in Cinebench R23 multi-core, where the Intel Core i7-1270P scores 13,938 against the Ryzen 5 7535U’s 8,591. That is a 38.4% advantage for Intel, an enormous margin that reflects the Core i7’s 12-core/16-thread configuration versus the Ryzen’s 6-core/12-thread design. The older Cinebench R15 multi-core test shows a narrower gap, with Intel ahead at 1,404 versus 1,330, a 5.3% edge. Single-core performance flips in Cinebench R15, where the Ryzen 5 7535U wins 225 to 198, a 13.6% lead. However, in Cinebench R23 single-core, Intel reverses the result dramatically, scoring 1,967 against AMD’s 1,414, a 28.1% advantage.

Beyond Cinebench, the PassMark suite reveals a split along workload types. Intel wins floating-point math decisively, scoring 43,168 versus AMD’s 33,971, a 21.3% margin. Intel also takes physics simulation, with 1,120 to AMD’s 839, a 25.1% gap, and prime number finding, scoring 66 to 50, a 24.2% lead. Integer math is nearly a tie, with Intel edging ahead 63,016 to 62,109, just 1.4%. Single-thread PassMark results favor Intel modestly, 3,354 to 3,203, a 4.5% edge.

AMD’s strongest victories come in areas that stress instruction-level parallelism. The Ryzen 5 7535U scores 13,187 in extended instructions, beating Intel’s 10,575 by 24.7%. Data encryption shows AMD ahead 12,706 to 11,276, a 12.7% margin. Data compression favors AMD at 200,252 versus 184,917, an 8.3% gain. Random string sorting also goes to AMD, 21,267 to 20,546, a 3.5% edge. The PassMark multi-thread score is essentially a dead heat, with AMD at 17,039 and Intel at 16,957, a 0.5% difference that falls within noise.

The Verdict

The data points to a clear split: the Intel Core i7-1270P is the processor to choose for heavily multi-threaded productivity, 3D rendering, and scientific computing. Its 38.4% lead in Cinebench R23 multi-core and 21.3% advantage in floating-point math make it the stronger candidate for workloads that scale across cores and benefit from high FP throughput. The Intel part also wins in single-threaded Cinebench R23 by 28.1%, suggesting better raw per-core performance in that benchmark.

The AMD Ryzen 5 7535U is the pick for security-related tasks, compression workloads, and any application that leverages extended instruction sets. Its 24.7% win in extended instructions and 12.7% lead in encryption indicate strong SIMD and cryptographic performance. The 8.3% compression advantage also makes it suitable for file archiving and database workloads. For general multi-threaded PassMark performance, the two processors are effectively identical, with AMD holding a 0.5% edge that will not be perceptible in real-world use.

The overall average benchmark scores place both processors at the 76th percentile among all CPUs. The Ryzen 5 7535U averages 22,791, while the Core i7-1270P averages 22,502, a difference of roughly 1.3% in AMD’s favor. Both sit near comparable rivals: the Ryzen 5 7535U is 0.1% behind the Ryzen 5 2600X and 0.5% behind the Ryzen 5 6600U, while the Core i7-1270P is 0.2% ahead of the Core i5-13500H and 1% ahead of the Ryzen 5 220.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 7535U uses the Zen 3+ architecture on a 6 nm TSMC process, with the Rembrandt-R codename. It is built on a 208 mm² die. The Intel Core i7-1270P uses Alder Lake architecture on Intel’s 10 nm process, with the Alder Lake-P codename and a 217 mm² die. The process node difference is significant: 6 nm versus 10 nm, which typically allows for better power efficiency per transistor on the AMD side.

Cache hierarchies differ substantially. The AMD chip has 64 KB of L1 cache per core and 512 KB of L2 per core, with 16 MB of shared L3. The Intel chip has 80 KB of L1 per core and 1.25 MB of L2 per core, with 18 MB of shared L3. The larger per-core L2 on Intel suggests better data locality for single-threaded workloads, while the larger total L3 may help with shared data across cores.

The integrated graphics also differ. AMD pairs the CPU with a Radeon 660M, while Intel uses Iris Xe 96EU. Both support PCIe Gen 4 with 20 lanes on the CPU side. Memory support distinguishes the two: the Ryzen 5 7535U supports only DDR5, while the Core i7-1270P supports both DDR4 and DDR5. AMD also lists ECC memory support, which Intel does not offer on this part.

Specification Differences

The core and thread counts are the most obvious differentiator. The Intel Core i7-1270P has 12 cores and 16 threads, double the core count of the Ryzen 5 7535U’s 6 cores and 12 threads. Clock speeds differ in both directions: the AMD chip has a higher base clock at 2.90 GHz versus Intel’s 2.20 GHz, but the Intel chip has a higher boost clock at 4.80 GHz versus AMD’s 4.55 GHz.

Both processors share a 28 W TDP and are locked (multiplier not unlocked). They use different sockets: AMD Socket FP7 for the Ryzen 5 7535U and Intel BGA 1744 for the Core i7-1270P. Memory bandwidth is listed at 76.8 GB/s for the AMD chip, while the Intel chip’s memory bandwidth is not specified in the data. The Ryzen 5 7535U was released on January 3, 2023, while the Core i7-1270P launched earlier on February 22, 2022. Both are mobile market segments and remain in active production.
