The new Steam Machine console, developed by Valve under the code name Fremont, appears again in Geekbench performance tests after 10 months.

However, this time, a very critical detail stands out in the leak: The tests no longer run on Windows, but directly on SteamOS, the built-in operating system of the device.

These new results, uploaded to the database on June 15, 2026, strongly indicate that the development process has reached its final stage and the device has begun to be tested in the hands of technology editors.

Why Are SteamOS Tests Valuable?

Two new records appearing in the Geekbench database are making a big impact in the hardware world.

In the first Fremont tests held in August last year, the system was running on the Windows operating system. The fact that the tests are now carried out directly on SteamOS shows that the product has passed the prototype stage and is being tested in the final software environment that will reach the end consumer.

In particular, the presence of booster codes for new generation devices in the SteamOS 3.8.9 Beta version that Valve recently released reinforces the accuracy of this leak. Public sources believe that the review units have already reached members of the media and that a test user accidentally synced the device to the database.

Details of AMD Signed Custom Processor

The new Steam Machine contains a specially produced chip coded as “AMD Custom CPU 1772” at its heart. According to Geekbench information, this processor is based on AMD’s powerful Zen 4 architecture.

The hardware, which comes with 6 cores and 12 threads, offers 16 MB L3 cache. The chip, whose base frequency is around 3.2 GHz, can reach very fast speeds such as 4.86 GHz under load.

When we look at the performance scores, the device scores 2,334 points in single-core tests and reaches 7,392 points on the multi-core side.

Although these results are inconsistent with existing Windows tests, they prove the stability and power of SteamOS optimization. The processor, which is thought to have a 30W TDP, exhibits a performance that is on par with the high-end Ryzen Z1 chips we see in portable handheld consoles.

Twice as Powerful as Steam Deck

Examining the test scores in more detail, it appears that the Fremont outperforms current generation home consoles such as the PlayStation 5 in single-core.

Compared to the processor used in the Steam Deck OLED model, the new Zen 4 architecture chip offers almost twice as much processing power.

This huge leap heralds that Steam Machine will not only play modern AAA games smoothly on the giant television screen in your living room, but will also provide a flawless experience with advanced emulation software that requires heavy CPU power.
