Hardware support: PlayStation 5 New Details From Mark Cerny: Boost Mode, Tempest Engine, Back Compat + More

If we take 2 CPUs with similar clock speeds, can their power consumption be different? For example, if we run avx code on one while an avx2 code on the other, will they consume different amount of power? Can a situation arise where a CPU, or GPU, can complete a task in a certain amount of time, but the power consumption will overshoot the cooling capabilities and result in the CPU or GPU throttling?

MediaTek windows 10 devices?

Posted: 02 Apr 2020 06:32 AM PDT

So i had a thought, the issue with the qualcomm devices is the cost, which exists in the android world too, with qualcomm you get a strong GPU and good power efficiency... but is this really needed with windows devices? We need strong CPUs (which MTK can do), strong GPUs are a waste really on WoA devices (windows on arm), as there are no games on the win10 store!

Imagine, 12hr battery, instant on, competitive performance with Intel Pentuim/Celeron CPUs, with a mediatek cpu running the show? At a low enough pricepoint these machines will be bought by people who only do basic tasks anyway.. Is this the new eee pc revolution?

A Helio G90T for example, strong CPU performance, lacklustre (compared to 855) GPU but still strong enough for good 2D graphics. In a $500 machine? That will sell like hotcakes. Maybe MTK could make a chip that has 4K display out capabilities that could help out with HDMI 2.0.

Will the Lockhart(Series S) have reduced ray tracing,bandwidth,storage and be difficult to manufacture and develop games for? (Speculation)

Posted: 01 Apr 2020 06:58 AM PDT

Ray Tracing and CU

Most rumors points to the existence of 4TFlops Series S(lock hart) console.The Series X has 12 TFlops and 52 CU@1.8GHz to achieve that performance.Scaling down, the Series S will need 18CU@1.8GHz to get 4 TFlops. Series X will target 4K and Series S will target 1080p.Both consoles are supposed to have same rendering effects,features,etc but only at differing resolutions.The 4 TFlops are more than enough for 1080p gaming and having feature parity.Each CU will have its own RT core(Ray Tracing). Will 18 RT cores be enough for Series S to have feature parity at 1080p compared to Series X at 4K with 52 RT cores?

RAM and Bandwidth

The original lock hart and anaconda rumors in 2019 highlight Series S having 12 GB GDDR6.12 GB would be ideal as it is the same amount of memory as One X which will be familiar for developers.Also,the 12 GB can be arranged as 6 2GB RAM chips which would lead to bandwidth of 336GB/s.This bandwidth is exactly equal to slow bandwidth(6GB at 336GB/s) of Series X. Microsoft said the CPU data such as game scripts can be placed in slower RAM. So both series X and series S will have their CPU data accessible at same speeds and will lead to easier programming for developers.But Dealer Gaming is insisting that Series S will have reduced ram from original spec.He says that there will be 8GB of GDDR6 instead of 12GB to reduce cost of the console.The 8GB can be arranged similarly to PS5.Instead of the eight 2GB chips used in PS5,series S will use eight 1GB chips and will have same bandwidth of PS5 at 448GB/s.The bandwidth is higher than above 12GB configuration but the amount of texture that be stored will be lesser than One X..This low availability and varying bandwidth of RAM could be countered by faster SSD speeds, but might lead to some learning curve among developers.

SSD size

Most rumors points to Series S being a Digital only console without a Disc drive.Will the SSD size be 500GB instead of 1TB so that Microsoft can reduce costs? A well known issue among SSD is that their performance suffers heavily when it is almost filled(85-90% full). The read and wire speeds fall to almost hard disk levels and it will damage the NAND flash cells because of overwriting in the remaining cells.The 1 TB model can mitigate this but a 500 GB model might have high difficulty finding a way around this.The only solution will be taking a good chunk of the SSD for the OS and wear leveling,leaving around 300-350GB of usable storage.Will this storage be enough considering there is no disc drive?I am looking for suggestions on how Microsoft may tackle these challenges and keep down the cost of console to the rumored amount of $300.
