Question About GPU of Mac pro with Photoshop CC.

1.Radeon Pro 580X (with 8GB GDDR5 memory) 2.Radeon Pro Vega II (with 32GB HBM2 memory) 3.Radeon Pro Vega II Duo (with 2 x 32GB HBM2 memory)
I do not edit videos. Just edit one image of 200GB-400GB with photoshop. (thinking of 28 cores for CPU and 756 GB for RAM.) This question should be to apple, but as a result of inquiring, I do not have detailed information from apple and will contact adobe community.

 

Thank you,

Agree. This is excessive beyond overkill.

 

Photoshop is mainly limited by system I/O, how much data it can move around and how quickly. The most critical component is the scratch disk, but a standard 1TB NVMe system drive will do splendidly. Those files aren't particularly big. Big would be, say, 5 - 15 GB, in which case you might consider 2TB or more.

 

Other than that, an 8/12-core i7 or i9, 32 GB RAM, and a video card with 4-10 GB VRAM is plenty enough. Beyond that there's no return on investment.

    Hi Mr.D_Fosse,
    Thank you for your advice.


    I still think of RAM, under less around 500GB is not enough for my work. Because this year I used iMac pro(18 core, 128gb_RAM,4TB_SSD) for 6 months, then Photoshop always needs 'Scratch disk' even in my date occupied 200-600GB of 4TB in SSD. It means RAM 128GB is not enough at all and even 3.5TB space for 'Scratch disk' is still not enough. Today I opened one image which has 280GB on photoshop. Checked 'Document size'. It indicated 324GB when it includes full layers. After some tasks, it became twice soon. 

    So I am still thinking about RAM I need 768GB at this moment. Anyway, Thank you so much quick advice.

    I appreciate such a community. We don't have like this in Japan. Helping me a lot.
    Thank you again,

    best,

    Hiro

    768GB のメモリはあまりにも高価ですから OWC Express 4M2 NVMe M.2 SSD 4slot Thunderbolt 3 などの外付けケースで RAID 0 をスクラッチにしたらいかがでしょう。RAID 0 ならチャンクサイズも自由に設定できます。

    私は Thunderbolt 3 の SSD x 2 をチャンクサイズ 256 k にして使っています。

    （と言っても 32 K と 256 K の差が体感できるほどのことはしていませんが...）

    それとジャーナリング無し、スポットライト対象から外すなどのことにより、余計な読み書きが発生しないのもメリットですね。

    Hi

    The Radeon Pro 580X with 8GB GDDR5 would be sufficent for Photoshop, 756GB of RAM is overkill

      Hi Ged,
      Thank you for your advice, the link is really helping me.
      Now I got to know how much power of GPU I need. It is really good information for me.


      But I still think of RAM, under less around 500GB is not enough for my work.

      Anyway, Thank you from Japan.
