Intel Core i5-1145G7 vs Intel Celeron N5095 vs Intel Core i5-1155G7

Intel Core i5-1145G7

The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).

Another novelty is the integrated Xe graphics card 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).

Furthermore, 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. In addition to this, the i5 supports vPro for easy remote management.

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

Intel Celeron N5095

The Intel Celeron N5095 is a quad-core SoC of the Jasper Lake product family designed for use in affordable SFF desktops and laptops. The Celeron was announced in early 2021. It features four Tremont CPU cores running at 2 GHz (base clock speed) Boosting up to 2.9 GHz (single-core Boost) with 1.5 MB of L2 and 4 MB of L3 cache but no thread-doubling Hyper-Threading technology. This processor is manufactured on Intel's first-gen 10 nm process to be not unlike the Ice Lake-U Core-series processors. The faster Celeron N5105 is notable for being more energy efficient (10 W TDP vs N5095's 15 W) yet featuring a faster iGPU model (24 EU UHD Graphics versus 16 EU UHD Graphics, with a higher clock rate to boot).

Architecture

Tremont architecture brings many improvements over the outgoing Goldmont architecture we know from Pentium N5030 and so many other N-class CPUs. According to Intel, the new architecture brings a 30% boost in single thread performance (+10% to +80% in SPECint and SPECfp depending on the test).

While the older N-class Celerons and Pentiums had to be content with up to 8 GB of DDR4-2400 RAM, Celeron N5095 is officially compatible with up to 16 GB of dual-channel DDR4-2933 or quad-channel LPDDR4x-2933 memory. Wi-Fi 6 (Gig+) support is partially baked into the chip. The Celeron supports up to 8 PCI-Express 3.0 lanes, up to 14 USB 3.2 ports and up to two SATA III ports. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s, provided a suitably fast NVMe SSD is used.

Jasper Lake processor package is larger compared to what Gemini Lake models had (35 x 24 mm vs. 25 x 24 mm). Please note that the Celeron gets soldered on to the motherboard (BGA1338 socket interface) and is thus not user-replaceable.

Performance

The average N5095 in our database matches the Core i3-10110U, Core i3-1005G1, Celeron N5105 and also the Ryzen 3 3200U, as far as multi-thread benchmark scores are concerned.

Even if the cooling system is great and the Power Limits are high as the sky, some slight architectural improvements together with the updated manufacturing node and higher-than-usual wattage of the Celeron are not nearly enough to let it compete with modern Core and Ryzen-series processors. It's a good option for basic day-to-day tasks, but anything beyond that will be a struggle.

Graphics

The CPU features the DirectX 12-capable 16 EU UHD Graphics iGPU running at 450 MHz to 750 MHz. The graphics adapter is capable of driving up to 3 displays with resolutions up to 4096x2160@60; it will happily decode HEVC, AVC, VP9, MPEG-2 and other popular video codecs. The latest AV1 codec is not supported, though. (You can still play such a video but it will be software-decoded rather than hardware-decoded which puts a hard limit on the watchable resolution as the CPU cores are not very fast here.)

This is not a gaming GPU by any stretch of imagination. It is just as fast as an HD Graphics 515; it will let you play the least demanding titles (like Dota 2 Reborn) provided you are OK with 720p resolution and lowest quality preset possible.

Power consumption

Most N-class Celerons and Pentiums have a 6 W TDP (also known as the long-term Power Limit). The Celeron N5095 on the other hand has a 15 Watt TDP to mimic much faster U-class Core i3/i5/i7 processors. This basically means that passively cooled designs are out of the question with this chip.

This Intel processor is manufactured on Intel's first-gen or second-gen 10 nm process [no precise data available] for OK, as of late 2022, energy efficiency.

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.
