Except it might be very relevant, because it's all relative. Imagine the following scenarios.
Lockhart, 4 Tflops - $299
PS5, 10.28 Tflops - $399
XSX, 12.15 Tflops - $499
PS5 would get you 157% more performance for $100, whilst the XSX would get you 18% extra for $100. Suddenly the PS5 is looking like a steal, and Lockhart a bit of a dud. The XSX's performance advantage is also looking like a pretty bad deal.
Potentially more realistic pricing.
Lockhart, 4 Tflops - $349
PS5, 10.28 Tflops - $449
XSX, 12.15 Tflops - $499
PS5 would get you 157% more performance for $100, whilst the XSX would get you 18% extra for $49. The PS5 is still looking like a steal, and Lockhart still a bit of a dud. XSX's performance advantage is looking like better value proposition.
And then the worst case for Sony, but that is still a possibility.
Lockhart, 4 Tflops - $349
PS5, 10.28 Tflops - $499
XSX, 12.15 Tflops - $499
PS5 would get you 157% more performance for $149, whilst the XSX would get you 18% extra for no added cost. Lockhart is looking like a better proposition now, but $149 extra for so much more performance from the other two still seems worthile, the XSX especially. Notably if buyers expect to get a 4K screen to replace their 1080p one, any time in the next several years.
