The custom drive solution should allow sony 1st party to do some cool stuff that can't be done on PC or Xbox. The power difference is there but smaller than last gen between xb1 and ps4 or xb1x or ps4 pro. One concern over sony gimping the GPU will be ray tracing performance.

No way. They may throw together some bundle to get the price to $600, but that's a price tag that no one wants.

i said the same thing at first since getting over $500 is a huge mental hurdle for most people, but the more I've read, the more I've seen people claim that MS would be taking a MASSIVE loss at anything less than 600

The variable frequencies and restricted power envelope is going to cause additional frustrations for developers to optimize their games. It's not an elegant solution.
It's utilizing AMD's SmartShift tech, meaning power is dynamically shifted between the CPU and GPU. If the GPU is running at max clocks (2.23 GHz in this case), the CPU is throttled by an equal percentage. The CPU and GPU can't run at max clocks concurrently. The wattage is constant throughout the system, so more watts into the CPU to push clocks higher results in GPU throttling, and vice versa.
Now we know why Microsoft placed such an emphasis on sustained clocks for the CPU/GPU in their marketing materials.
There was also surprisingly little information on RT, and nothing on VRS. The low CU count on the GPU will almost certainly hurt the system when it comes to RT performance.

What does this mean?

The PS5 has a superior SSD implementation built from the ground up. Allows for more data to be stored in RAM while compressed, they'll be able to stream a ton of detail and get it where it needs to go faster.
As fast as any NVMe SSD on the market (if not the fastest), which they said a few months ago and is indeed true.
Xbox IO throughput is 2.4GB/s to the PS5's 5.5GB/s, and compressed 4.8GB/s to PS5's ~9GB/s. Roughly double the speed.

599.00 for Series X
299.00 for Series S (Lockhart)
499.00 PS5
Just my guess
Posted on 3/18/20 at 11:00 pm to ThuperThumpin
Nah. I think they both go $499

Wii U was PowerPC CPU and AMD GPU.
Posted on 3/19/20 at 12:55 am to The Quiet One
You know about an hour later after posting about the WiiU and no PowerPC I thought about how AMD was GPU only and it had a 2xCore PowerPC CPU (I think)
Too late I guess

Can't say how much it will matter to me but developers seems to be extremely happy with the PS5 SSD. Way more than a TF total. Seems that it will help them out a lot. But I would assume any 3rd party games couldn't take advantage of it fully.

Well, it goes way past being just an SSD. Most of us installed SSDs in this gen consoles, but on a SATA2 interface.
nVME and increased BUS width are the biggest differences.

PS5 seems geared for speed. Mark was specific on how devs can program just like they did for PS4 and it’ll perform just fine, but they also could toy with the whole “boosting” thing to maximize performance. Boot times, load times, install times, patch times...all of these were stressed as core competencies of the PS5. Hell, even the best NVMe SSDs on the market right now can’t handle the PS5’s architecture. Pretty advanced work for a mere console. We have to wait on the PC market to catch up.
Sony really needs to nail it with their services, though. Their store sucks. PSNow sucks. PS+ sucks with some exceptions when they manage to offer a decent free game (is it free when I pay a monthly fee?).

Oh I know. I read up all about it. How it will help on the development side of things. Just want to see if it is pushed to the limits they are so excited about.

Still tripping about this #PS5 SSD spec. Like, people don’t even know how big of a leap in terms of game design can be made, especially for 1st party that doesn’t have to design to lowest common denominator. By far the biggest leap in my career. Can’t wait.

The craziest thing about PS5 is the speed of the SSD. 5.5 GB/s is just part of the story - there is a lot of custom silicon in there to ensure that the system isn't bottlenecked in other areas. It's *REALLY* fast on paper - a lot faster than Xbox Series X even.
It's not about load times. It's about accessing data super fast on the fly. It can change how worlds are designed. It's a fundamental shift.

I'm still extremely disappointed in the GPU specs.
Posted on 3/19/20 at 10:38 am to LSU Coyote
It would be nice to have everything. I agree. But I will pay whatever. I am not sure the casuals will.

The digital foundry guys said the PS4 specs are more ambitious. Graphically you won’t see much of a difference at all

That's not how it works.
The PS5 has a static instruction allocation budget for the CPU/GPU. If developers are throwing out a lot of computationally intensive instruction sets, the system deterministically lowers clocks to stay within a preset thermal envelope. This allows them to save costs on a cooling solution.
It's not ideal, and it's going to require extra work from developers to rework their code around these restrictions.
