Intel Pentium Gold 7505 vs Intel Core i7-1185G7 vs Intel Celeron 6305

Intel Pentium Gold 7505

The Intel Pentium Gold 7505 is a power-efficient dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in the third quarter of 2020. Unlike many other TGL-UP3 processors, the Pentium features an Infrastructure Processing Unit (Intel IPU). It integrates two Willow Cove processor cores (4 threads thanks to HyperThreading) clocked at 2 - 3.5 GHz (at 15 Watt TDP).

Another novelty is the integrated Xe graphics adapter based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older UHD Graphics G1 (Ice Lake).

Other improvements from Ice Lake are also integrated in Tiger Lake like the AI hardware acceleration and the partial integration of Thunderbolt and WiFi 6 in the chip.

Performance

The average 7505 in our database lags just slightly behind the N95, as far as multi-thread benchmark scores are concerned. In other words, this is an entry-level chip that's good enough for basic day-to-day activities only, as of late 2022.

Power consumption

This Pentium series chip has a default TDP (also known as the long-term power limit) of 15 W. Which is a tad too high to allow for passively cooled designs.

The Intel Pentium 7505 is built with Intel's 3rd generation 10 nm process marketed as SuperFin for low, as of mid 2023, energy efficiency.

Intel Core i7-1185G7

The Intel Core i7-1185G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was introduced September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 1.2 GHz (12 W base clock speed), 3 GHz (28 W base clock speed) to 4.8 GHz (single-core boost). All cores at once can clock at up to 4.3 GHz. At the time of announcement, the i7-1185G7 is the fastest model of the line-up. Since early 2021, the i7-1185G7 supports management features like vPro.

Another novelty is the integrated Iris Xe iGPU based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i7-1185G7 it uses 96 EUs and clocks between 400 - 1,350 MHz. The GPU and CPU can together use the 12 MB of L3 cache.

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

Performance

The average 1185G7 in our database is just as fast as AMD's hexa-core Ryzen 5 4500U, as far as multi-thread benchmark scores are concerned. While the i7 is not the fastest Tiger Lake chip by any stretch of imagination, it's more than usable for your productivity and creative apps, with a bit of gaming possible as well.

Thanks to its decent cooling solution and a long-term CPU power limit of 55 W, the Stealth 15M A11SEK is among the fastest laptops powered by the 1185G7 that we know of. It can be almost twice as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This little Core i7 here has a default TDP of 12 W to 28 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. Either way, that's a tad too high to allow for passively cooled designs.

The chip is manufactured on Intel's third-gen 10 nm process marketed as SuperFin for average, as of late 2022, energy efficiency.

Intel Celeron 6305

The Intel Celeron 6305 (or 6305U) is a power efficient dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in the third quarter of 2020. It integrates only two Willow Cove processor cores (2 threads - no Hyper-Threading/SMT). The clock speed is set at 1.8 GHz as the chip does not support Turbo Boost.

Performance

The average 6305 in our database is in the same league as the Celeron N4505, as far as multi-thread benchmark scores are concerned. This is a very poor result, as of late 2022.

Your mileage may vary depending on how high the CPU power limits are.

Another novelty is the integrated Xe graphics фвфзеук based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older UHD Graphics G1 (Ice Lake). In the 6305U Intel calls it just UHD Graphics and it offers 48 EUs.

Other improvements from Ice Lake should be also integrated in Tiger Lake like the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip.

The chip is produced on the improved 10nm+ process (called 10 nm SuperFin) at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
