    7970 has 8 RBE x 24KB (per RBE)=192KB
    X1X has 8 RBE but per RBE is not 24KB but 256KB
    why? because RBE is not just RBE it is fabric L2
    same as Vega,RBE is client to L2
    means 8 RBE represent 4 SE(GPU1) + 4 Sh Array (GNB) are from 2 different GPU block, inline with birdie

            cross linked to what i said mny times

            focus on slide 1 and 2
            slide:
            1:
            SideALU -> to aid,vectorized
            2:
            2 Inst,VLIW2 (because it is from point 1)
            means from whole host perspective simultan 2 Command
            because Norm GPU is only one

              -nintento nope (Nvidia)
              -recent Subor, nope just AMD APU in 12nm very norm

                New PS5 Rumor as we enter the Day 3 of GDC 2019. This rumor claims that the PS5 has;
                9.216 Teraflops of GPU power
                12GB of GDDR6 + 4GB of DDR4 (16 totall)
                8 Core/16T Ryzen (+) CPU
                Sony still aiming at $399 price tag

                (Take it with grain of salt)





                this wont be posted on forum because the number bit low
                but this is the actually quite logical
                this is what I posted on twit too
                PS4 = 0.8 Ghz
                PS4pro= 0.9 Ghz
                PS5 logically 1-1.1 Ghz

                so no wonder recent leaked PS5 from GDC is about 9.7 TF
                let said it is 72 CU
                72 x 64 x 2 x 1.05 Ghz = ~9.6 TF
                at 1 Ghz it is ~9.2TF
