Intel Core i5-1155G7 vs AMD Ryzen 7 5700X vs AMD Ryzen 7 5800X

Intel Core i5-1155G7

The Intel Core i5-1155G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in mid 2021 as part of the refresh. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1 GHz (12 Watt TDP) up to 2.5 GHz (28 Watt). Boost clock speed is 4.5 GHz.

Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip.

Another novelty is the integrated Xe graphics adapter with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).

Performance

The average 1155G7 in our database proves to be a very decent mid-range processor, as of mid 2022, trading blows with the Core i7-10810U and the Ryzen 5 4500U as far as multi-thread benchmark scores are concerned. While perhaps not the best option for power users, this Core i5 will make most consumers happy, providing for short load times and generally pain-free experience.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

Power consumption

This Core i5 series chip has a default TDP, also known as the long-term power limit, of 12 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, this is a tad too high to allow for passively cooled designs.

The i5-1155G7 is built with Intel's third-gen 10 nm process marketed as SuperFin for lower-than-average, as of early 2023, energy efficiency.

AMD Ryzen 7 5700X

AMD Ryzen 7 5800X

The AMD Ryzen 7 5800X is an 8-core desktop processor with Simultaneous Multithreading (SMT), which allows it to process 16 threads simultaneously. With its launch on 08.10.2020, it is the fastest 8-core processor from AMD. The second fastest 8-core processor will be the AMD Ryzen 7 3800XT, followed by the more economical AMD Ryzen 7 3700X, also with 8 cores and 16 threads.

The Ryzen 7 5800X clocks with a base clock of 3.8 GHz and reaches up to 4.7 GHz on one core in turbo mode. When all 8 cores are utilized, the AMD Ryzen 7 5800X, like the AMD Ryzen 9 5900X, achieves up to 4.5 GHz.

At first glance, the internal structure of the processor has not changed fundamentally. The CCX structure has changed somewhat compared to Zen2, because now a CCX consists of up to 8-CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity-Fabric should now reach clock rates of up to 2Ghz, which in turn allows a RAM clock of 4.000 MHz without performance loss.

Performance

The average 5800X in our database is in the same league as the Core i9-10900K and also the Core i7-12700F, as far as multi-thread benchmark scores are concerned.

In games, AMD's Ryzen 7 5800X can convince with its significantly improved IPC and even put Intel in its place. With the AMD Ryzen 7 5800X, gamers are well prepared for the future as simultaneous streaming is no problem with the new Ryzen 7 5800X. Semi-professional content creators, who need even more power, can choose a Ryzen 9 5900X or the Ryzen 9 5950X on the shelf.

Power consumption

The Ryzen 7 has a default TDP (also known as the long-term power limit) of 105 W. This applies as long as the CPU runs at stock clock speeds.

Ryzen 7 5800X is built with TSMC's 7 nm process; as rumors have it, the I/O die is manufactured separately on the 12 nm Global Foundries process.
