XBOX ONE SERIES X SPECS

The full specs for the Xbox One Series X is now available, it’s about double the performance over the current Xbox One X.

  • CPU: 8 cores 16 threads Zen 2 at 3.8GHz (3.6GHz with SMT enabled)
  • GPU: 12 TFLOPs, 52 CUs at 1.825GHz, Custom RDNA 2
  • Die Size: 360.45 mm²
  • Process: TSMC 7nm Enhanced
  • Memory: 16GB GDDR6
  • Memory Bandwidth: 10GB at 560GB/s, 6GB at 336GB/s
  • Internal Storage: 1TB Custom NVMe SSD
  • IO Throughput: 2.4GB/s (Raw), 4.8GB/s (Compressed)
  • Expandable Storage: 1TB Expansion Card
  • External Storage: USB 3.2 HDD Support
  • Optical Drive: 4K UHD Blu-ray Drive
  • Performance Target: 4K at 60fps – up to 120fps

The basic block diagram shows how the console is configured. The system on a chip is common now with modern hardware integration designs. The GDDR6 is same as is found on contemporary PC display adapters.

Costs have risen with the Xbox One S and the most recent Xbox One X. Now the cost for the Xbox Series X becomes even more expensive. The total size of the Xbox SoC is 360 mm2, down slightly from the 375 mm2 of the Xbox One and the 367 mm2 of the Xbox One X. 

The Xbox Series X CPU is a dual CPU design. This how AMD designed the Zen 2 where separate CPU modules are used.

Microsoft has also stated that it aims to release games that target 4K and 60 frames-per-second as a standard. The spec sheet also reconfirms that the console will target 120 frames-per-second for some titles and support variable refresh rate displays.

Microsoft said the clock speeds on the CPU are locked and are not adjustable. Curiously, developers can choose to run with eight physical cores at the higher clock, or all cores and threads can be enabled with a lower 3.6GHz frequency. There are no boost clocks with Xbox Series X.

Now that the graphics are known it makes it easier for PC gamers to match or exceed the console. It is not known if the logic for the console is using a chiplet design similar to the R5 2400G.

PCI Express 4.0 has double the bandwidth of PCI Express 3.0 which the R5 3600 natively supports. The R5 3600 has slightly fewer cores compared to the console but double the memory with 32 GB installed. The large L3 cache is a big advantage for the PC processor and the turbo boost is another advantage. A new CPU may be procured primarily now that 5 nm hardware is pending.

This leaves the graphics card as the primary area to focus on. Speculation that AMD has a higher performance graphics card to compete with the new nVidia cards have suggested PC gaming has no worries. The goal is for a video card with 16GB of VRAM to match the console seems appropriate.

A new feature for the Xbox is the quick resume. This can allow a person to continue a game immediately. Loading times for games are not that long but impatience is an issue. Larger capacity SSD drives are now more widely available.
