Specs

• Custom AMD Zen 2 CPU with eight cores clocked at 3.8GHz each
• AMD RNDA 2 GPU with 12 teraflops and 52 compute units clocked at 1.825GHz each
• Both 7nm
• 16GB of GDDR6 RAM (total width of bus is 320 bits)
  • 10GB seems to be wired to GPU
  • 6GB to CPU
• 1Tb of very cheap QLC SSD
• 1TB expansion cards (seems to be fully custom)
• USB 3.2 external HDD support
• 4K Blu-Ray
• HDMI 2.1 support

One thing that this means is that even moderate 8 core system with 1080 Ti or RTX 2080 will do the same or better.

Most probably console will be first known for thermal throttling and dynamic resolution changes related to it.

Bad thing is that 2 in 1 (GPU+CPU) solutions are very bad design in modern times due too much TDP.

Also note that within 1-1.5 years 16Gb GPU will be pretty middle range, and 8 core CPUs will take place of old 4 core ones suggested for beginner gamers machines (while 16 cores becoming new middle and 32 core the top in consumer line).

Microsoft is using a special proprietary expansion card, and it has teamed up with Seagate to launch 1TB expansion cards for the Xbox Series X.

Corporations never change.

Xbox Series X will arrive in November and will set you back $499.

299 for 4 teraflops sound like nothing, but the system as a whole sound nice!!!
