Intel Core i5-1340P vs AMD Ryzen 7 7730U vs Intel Core i7-1370P

Intel Core i5-1340P

The Intel Core i5-1340P is a mid-range Raptor Lake-P (Alder Lake-P refresh) family CPU, a 28 W part meant for use in ultra-light, ultra-thin (yet actively cooled) laptops. This CPU was announced in early 2023 and it has 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled and clock from 1.9 GHz (base) up to 4.6 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The clock speeds of the E-cores ranges from 1.4 to 3.4 GHz and offer a similar performance as the old Skylake cores.

The performance should be similar to the old Core i7-1250P and therefore well suited for even demanding tasks.

The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The i5-1340P is rated at 28 Watt tDP (PL1, 64 Watt PL2 for short bursts). The CPU is manufactured in the further improved Intel 7 process (10nm SuperFin).

AMD Ryzen 7 7730U

The AMD Ryzen 7 7730U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers the same specifications as the old Ryzen 7 5825U. The CPU integrates all eight cores based on the Zen 3 microarchitecture clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 7nm at TSMC.

The Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2 but stays behind the current Zen 4 based CPUs (e.g. 7040HS series).

Performance

The average 7730U in our database is in the same league as the Ryzen 7 5825U, Ryzen 7 6800U, Ryzen 7 PRO 6850U and also the Core i7-1360P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the ThinkPad E14 G5-21JSS05C00 is among the fastest laptops built around the 7730U that we know of. It can be almost 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

The TDP of the APU is specified at 15 Watt (the 5825U was specified at 10 - 25W). 

Intel Core i7-1370P

The Intel Core i7-1370P is the flagship Alder Lake-P CPU, which is to say, an expensive 28 W part meant for use in ultra-light (yet actively cooled) laptops. This CPU will probably be announced in early 2023 and it has 6 performance cores (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture) according to a leak on Geekbench. The P-cores are Hyper-Threading-enabled for whopping 20 threads when combined with the E-cores. The clock speeds can reach up to 5.2 GHz for the performance cluster (1.9 GHz base speed) and 1.4 GHz to 3.9 GHz for the efficiency cluster. The CPU is quite similar to the older Core i7-1280P but probably offers higher clock speeds.

Full vPro feature set is supported by this Core i7 ("Enterprise" tier, allowing for remote device management).

Architecture

The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little" Alder Lake core is supposed to be just as fast as a Skylake core (as found in the venerable Core i7-6700HQ among other options) which is six years old at this point. All of a Core i7-1280P's CPU cores enjoy access to 24 MB of L3 cache. The integrated memory controller supports up to 64 GB of LPDDR5-5200, DDR5-4800, LPDDR4x-4267 or DDR4-3200 RAM. Just like the other 12th Gen Intel Core processors, Core i7-1280P comes with Thread Director which is a new functionality designed to help Windows 11 decide which cores to use for what workload for best performance and efficiency possible. Hardware acceleration of AI algorithms is supported via GNA 3.0 and DL Boost (via AVX2). PCI-Express 5.0 support has not found its way into Alder Lake P processors, so users will have to be content with PCI-Express 4.0 for the time being. The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

Please note this is not a user-replaceable CPU. It gets soldered permanently on to the motherboard (BGA1744 socket interface).

Performance

Multi-thread performance is most comparable to AMD Ryzen 9 5900HS, Ryzen 9 PRO 6950HS, Intel Core i9-11980HK. Which is impressive but comes with a catch; long-term performance sustainability will be rather poor unless the Power Limits are very high and the cooling solution is a truly capable one.

Graphics

The built-in graphics adapter in the form of the 96 EU Iris Xe running at up to 1.5 GHz has seen no change from what was built into the 11th Gen Tiger Lake-UP3 processors, like a i7-1165G7, which is hardly a downside as this iGPU is loaded with modern features such as AV1 video decoding capability and SUHD 4320p monitor support. 

Power Consumption

The i7's base power consumption (also known as the default TDP value or PL1) is 28 W, with 64 W being its maximum Intel-recommended Turbo power consumption (also known as the PL2). The "Minimum Assured" power consumption is fairly high at 20 watts. All in all, an active cooling solution is nearly a must.

Core i7-1370P is built with Intel's third-gen 10 nm process marketed as Intel 7.
