Intel Core i5-1145G7 in 2026: Performance, Prices, and Comparison with Newer CPUs

The Intel Core i5-1145G7 is a Tiger Lake-generation mobile processor released in 2021 and widely used in business laptops. With four cores and eight threads, it already lags noticeably behind newer mobile processors in multi-threaded performance, but the i5-1145G7 is still fast enough for office work, web browsing, and development in single-threaded tasks.

In 2026, the Core i5-1145G7 is primarily worth considering in inexpensive refurbished laptops. Business models with this processor cost approximately €300-350, while laptops with faster 12th-generation Intel CPUs are already available for €400.

Performance in Real-World Laptops

Core i5-1145G7 performance depends significantly on the power limit, cooling, and memory configuration.

The prices apply to refurbished laptops and depend on the amount of memory, SSD, and the device’s condition. The configurations available for sale may differ from the systems used in the tests.

The HP EliteBook 830 G8’s multi-threaded result is approximately 44% higher than that of the EliteBook 840 G8, despite having the same processor. For mobile Tiger Lake, this difference between individual laptops is significant.

In Cinebench R23, the Core i5-1145G7 scores an average of approximately 1375 points in single-threaded mode and 4880 points in multi-threaded mode. The Dell Latitude 7420 scores 4769 points in Multi Core, while an Intel NUC with a higher power limit scores 4991.

In PassMark CPU Mark, the i5-1145G7 scores around 9,000 points. That is still enough for web browsing, office applications, IDEs, and basic photo editing.

Core i5-1145G7 vs. Core i5-1135G7

The Core i5-1145G7 and Core i5-1135G7 are based on the same architecture and have four cores, eight threads, 8 MB of L3 cache, and Iris Xe with 80 EUs.

The main difference is the higher maximum clock speed: up to 4.4 GHz on the i5-1145G7 versus 4.2 GHz on the i5-1135G7. In addition, the i5-1145G7 is aimed at business laptops and supports Intel vPro.

In Cinebench R23 Multi, the average score is approximately 4880 points for the i5-1145G7 and 4724 points for the i5-1135G7-a difference of about 3%.

Therefore, with the same laptop configuration, a significant premium for the i5-1145G7 is not justified. The battery’s condition, amount of memory, display, and price of the specific model matter more than this difference.

Core i5-1145G7 vs. Core i7-1165G7 and Ryzen 5 PRO 5650U

The Core i7-1165G7 is based on the same architecture and has four cores and eight threads. In Cinebench R23 Multi, it scores approximately 5110 points versus 4880 for the i5-1145G7-a difference of about 5%.

The Core i7-1165G7 uses Iris Xe with 96 EUs instead of 80 EUs, so the difference between the processors is more noticeable in graphics tests.

The Ryzen 5 PRO 5650U is noticeably faster in multi-threaded workloads. It scores approximately 6593 points in Cinebench R23 Multi-about 35% more than the i5-1145G7.

When compiling large projects and rendering, the four Tiger Lake cores already noticeably limit performance.

Iris Xe Graphics

The Core i5-1145G7 is equipped with Intel Iris Xe Graphics with 80 EUs and a clock speed of up to 1.3 GHz.

In the HP EliteBook 840 G8, the integrated graphics scores approximately 937 points in the Graphics Score test in 3DMark Time Spy. This is not enough for modern demanding games, but Iris Xe can handle video playback and processing, multiple monitors, and older or less demanding games.

Integrated graphics performance depends heavily on memory. With a dual-channel configuration, memory bandwidth is higher, so Iris Xe runs noticeably faster. Single-channel memory reduces FPS and graphics test results.

Power Consumption

For the Core i5-1145G7, Intel specifies a power configuration range of 12 to 28 W.

With good cooling and a high power limit, the processor maintains high clock speeds under load for longer. In thin systems with strict limits, performance can be noticeably lower.

How Much Does a Core i5-1145G7 Laptop Cost?

On the refurbished market, laptops with the i5-1145G7 are already priced close to models with newer processors.

At €300-350, the Core i5-1145G7 is still a reasonable choice if the laptop has 16 GB of memory, a 256-512 GB SSD, and a battery without significant wear.

At around €400 and above, it is worth considering the Core i5-1245U and other 12th-generation processors. The Core i5-1245U is noticeably faster in multi-threaded workloads and offers a more modern platform.

Conclusion

The Core i5-1145G7 is still powerful enough for office work, web browsing, studying, and programming. Single-threaded performance remains sufficient for everyday work, while Iris Xe is noticeably faster than older Intel UHD Graphics solutions.

The weak point of the i5-1145G7 is the multi-threaded performance of its four cores. In demanding multi-threaded workloads, this processor falls noticeably behind the six-core mobile Ryzen processors from the same period.

A reasonable price range for an i5-1145G7 laptop is approximately €300-350. At a higher price, it is better to look for a system with a Core i5-1245U, Ryzen 5 PRO 5650U, or a newer processor.
