It only took him 10 days to be right.

Lockhart still missing in action btw.
Didn't he say it would of been last tuesday. Maybe E3 cancellation stuff made the news go to this week. One week off. Better correct percentage then all those that said PS5 Feb reveal! :)

Tommy Fisher wins the prize for nailing the Xbox Series X specs:

He said 52CU at 1.82GHz on 12-14-19 and the final specs were 52CU at 1.825MHz.

No other person on NeoGAF nailed the specs so exactly.
I can't find anything before the 18th of December 2020. Can you link the exact quote?

Confused, is it a fixed allocation from a single pool of RAM? Part of the appeal of unified memory was that developers could split it any way, this almost reads like there's 6GB of DDR/system memory, but it also says 16GB of GDDR6, in which case why make a fixed pool?

I assume they were looking for more bandwidth, two pools give you more concurrent bandwidth. At least that's what I'm getting from the DF vid.

Report me if I continue to console war
So tommy fisher was right regarding to xsx gpu clockspeed and cu count, which pretty much confirms PS5 will be 52cus @ 2000mhz which would result in 13.3tflops.

This would mean the PS5 is 9.5% more powerful in the GPU.

We still dont know what the differences will be with CPU and Ram, so if ps5 has a lower clocked CPU, the differences would count each other out and the consoles would be even on power.

To put the power difference into perspective it would be like if the xbox one had the same memory setup as the ps4 and a 1.68tf GPU.

Games will perform the same.

Its great news both systems are beasts.

Yeah, Tommy Fisher > all other insiders so far. The guy even had clockspeeds right and we were all laughing him off.

So I imagine there's two missing numbers from the spec sheet

It says:
16GB GDDR6
10GB @ 560 GB/s, 6GB @ 336 GB/s

What we don't know is the GPU accessing the CPUs pool, and the CPU accessing the GPUs pool, probably at somewhat reduced bandwidth? It’s the whole idea of unified memory, going back to fixed pools probably isn't what they did, just takes a hit to move across pools.

This is quite detailed but of course my mind fixates on the remaining puzzles lol

It's a trade off between cost and bandwidth (at the same 16GB) - they could have gone 16 1GB chips for a 512 bit interface - huge bandwidth, but more cost not just the chips but extra die space for the 'channels' .. or they could have gone 8x 2GB chips for a 256 bit bus - less bandwidth, but cheaper.

The compromise just makes 6GB of the 16GB a bit slower than the rest .. ok when most of it is being used for OS . the rest of the 6GB can be used for less used assets.

Actually Tommy Fisher dropped some infos about that:

Just need to remind you things that i said before for the last time\
GPU: PS5>SeX ~10%
RayTracing Accelerators: PS5>X1 (PS5's RT works by using acceleration structures and algorithms much like nVidia's RTX cores)
CPU: Sex>PS5 ~ 6%
Memory: PS5>Sex for the size and bandwidth
SSD: PS5>Sex ~ Over twice as fast (this is the biggest and most noticable difference)
Fan noise (Dev-Kit): Sex>PS5 (not as egregious 1x vs. Pro).

BTW it's up to you believe me or not, but things gonna be clear very soon and you will find out who knows and who knows shit.

Bonus?
Remedy and Housemarque have been in Sony's WWS family for a while now!

Techland belongs to MS now!
 
if the ps5 has 2ghz gpu clocks then theres no way their cpu is at 3.8. that must have been the compromise.

So it seems it must be Ps5>GPU advantage and Xbox>Cpu advantage.

Not sure if either has any headroom to adjust before launch though.

Either Bloomberg was wrong about sony targeting $400 BOM or Tommy Fishers PS5 info is compromised.

Not really sure why Sony is still holding out at this point

As a PS fan the SX is an amazing piece of hardware, MS did a great job at making it, whether if the ps5 is 11TF or 13TF the difference will be within 10% so people on both side need to calm down & be happy.

As for Tommy Fisher some people need to apologise for him, he gave an accurate specs for SX.

It seems to be only a single pool.
They are splitting it via page allocation I guess (software).

Oh, that makes sense. So peak bandwidth would still be 500+ in that scenario.

Okay, that makes more sense than the way I was seeing it.

Nope



Nope

If you read the Excel spreadsheet you can see they are all for 3584 shaders, absolutely nowhere is it mentioned that the full chip would have 3840 or 4096 shaders, this is a assumption people have made based on previous consoles having binned chips. What we can probably deduce now is that 36 CU is likely the full on-chip CU count for Oberon/Ariel/Gonzalo rather than 40 that many have assumed.

GitHub never mentioned 60 CU’s total. Just 56 active. They most likely had all 56 active at time of testing.
Nope, the testing is 56 CUs, the console is 52 CUs, like what Tommy Fisher stated it to be.

So you’re telling me with the same logic that the PS5 is a 32 CU console? Stop it guys, you’re getting ridiculous at this point.....and funny 🤣🤣🤣🤣🤣🤣

Did anyone comment on the 4.8 GB/s transer speed for compressed data?? I feel it's really misleading. The transfer speed is 2.4 GB/s, if the data are compressed you may transfer even more data than 4.8 GB/s, but that won't be the norm, compressions have variable rates that depend on which type of data is being processed, so we cannot expect it to always reach 4.8 GB/s. I feel like Microsoft really fooled many people today. Maybe they estimated that the lowest ratio is around 2, so the transfer speed would be AT LEAST 4.8 GB/s for compressed data. Otherwise, Microsoft just put out a meaningless number.

Where tommy fisher, he got banned or what?
He was banned after he sent a very shitty shopped photo of the DS4 to Mod of War Mod of War and claimed it is a DS5.

Holy fucking shit I need to apologize to Tommy Fisher, he got the specs correct.
I would not automatically assume that everything is 100% legit with him. Naming the complete specs nearly down to the smallest detail and lying correctly is an achievement and actually shows that he knows something or knows someone who does. But the wrong pictures of the "DS5" remain questionable.

The decompression is done by hardware, so it isn't that misleading.

The one thing that was notably different from what some people were saying about the XSX was the RT. Seems the hardware accelerated RT functionality is very similar to what Nvidia brought forward (which isn't surprising since MS had at least some hand in that design).

Tommy absolutely nailed the Xbox Series X GPU specs. Not only did he get the CU and Clock speeds correct, he also clearly stated that Xbox Series X would be RDNA 2.0.

Whether he got the PS5 specs correct or not is still TBD. He may have had different sources for the Xbox and PS5 specs. His Xbox source was clearly spot on.

"Prepare to be absolutely blown away by not just revealing over 13 TFlops GPU power
for PS5 in PSM [2] February 2020."


XseX - 52 active CUs at 1.82Ghz ~ 12.1TFlops (RDNA 2.0)
PS5 - 52 active CUs at 2.0Ghz ~ 13.3TFlops (RDNA 2.0)


Custom AMD Zen 2-based CPU (8 cores @ 3.4 GHz)
Custom AMD Navi-based GPU (52 CU @ 2.0 GHz - 13.3 TF - RDNA 2.0)
APU on 7nm+/7nm EUV process, could explain the high clocks
8GB HBM2 + 16GB DDR4 RAM solution? (4GB DDR4 reserved for OS, power efficiency of HBM2 could be reason for higher GPU clocks)
NVMe SSD with custom controller (focus on read speeds, free CPU by integrated decompression)

I think the RAM and SSD parts are actually much much more interesting than the final TF count. We actually know very little about both PS5 solutions, not a lot of leaks in that direction. Maybe Sony is planning something special and tries hard to keep it secret? Thanks for the read if you made it this far.

Tommy Fisher said both are RDNA2 and both have 52 CUs, right?

So, both of them are RDNA2 and one of them is confirmed now 52 CUs^^
Tommy Fisher also said EXACTLY 12.1 RDNA 2 tflops, did he not?

Someone un ban his ass. :p
MS getting cocky gotta be awkward if tommy fisher was right haha
STILL "our most powerful console...."

Enjoy the meltdown if this is what you think validates your choice of console.

PS5

GPU-13.3TF RDNA2 + “secret sausage”

RTX Hardware + audio

CPU-3.7gh Zen 2

Memory-24gb (20gb DDR6+4Gb DDR4)

SSD 1tB/5gb+

Controller-haptic feedback, wireless charging, heart rate senzors

Webcam- something similar to Kinect



“You heard it here first!” 😈

Calm down, is just a speculation😁
