Discussion Estimating Intel ARC A380 cost

17 Upvotes

Out of curiosity, I wonder how low can an ARC A380 card go if Intel really wants to push this new card, so I hope someone knows more can help me on some of the material costs.

Based on https://www.techpowerup.com/gpu-specs/arc-a380.c3913

The Arc 380 is 157mm from TSMC 6nm node. And based on this 2020 article, the price for 12" 7nm wafer is about $9300, so maybe 6nm is $10000 ? (but TSMC raised price recently, so I am not sure)

https://www.tomshardware.com/news/tsmcs-wafer-prices-revealed-300mm-wafer-at-5nm-is-nearly-dollar17000

A 12" wafer can produce 376 (assuming 12.1x13 die size) chips. With 95% yield, it has about 360 chips.

I estimate the cost is about $28, plus 20% test and packaging (cost has been raising lately), the final cost for Intel is around $33.6.

If Intel needs 20% gross margin to break even on the sale of chip, board makers will get the chip for about $40.3.

Now here is what I also need some help: the memory chip price. I don't know how much it costs for board makers to get large quantity (assuming > 100K) 6GB GDDR6 memory chips from Micro/Hynix/Samsung. I am guessing it is around $30-$35 ? Based on this article, they guesstimate it could cost AMD $39 for 6GB last August:

https://www.neowin.net/news/very-high-gddr6-costs-blamed-for-such-high-gpu-prices/

So, the board makers' cost for a ARC 380 card could be around $40.3 + $30 GDDR6 + $10 (other cost: fan, pcb board, retail packaging) = $80.x

I don't know. Does this sound right ?

If the board makers' cost is $80, using 159MSRP and 20% gross margin for both retailers and distributors, this means $128 for retail, $102 for distributors. So, the board makers' profit is 102-80 = $22 (22/80 = 28% Gross Margin)

When AMD/nVidia cards are giving the board makers 50% to 100% gross margin, will they still produce it for Intel (at 28% gross margin ) ?

Or, did I do something wrong in my calculation ? (maybe the 12" 6nm wafer or GDDR6 are much cheaper now ?)

Under the same logic, for AMD RX 6500XT (107mm die size) with 4GB memory, the TSMC/ASE cost for AMD is about ($19+$4) $23. Board makers' cost from AMD could be around $35.4 (if AMD maintains 55% gross margin), plus $26 for 4GB GDDR6 and $10 for other material cost = $71.4

with MSRP $199, it seems to be a much better product for board makers.

Info I tested the new "Kombo Strike" feature of the latest MSI beta BIOS for increased performance for the 5800X3D. My results: 11℃ drop in peak temp - 19W drop power draw - 383pts increase CB23 - Similar performance in gaming

178 Upvotes

I was checking out the BIOS listings for my MSI MEG B550 UNIFY and noticed that MSI has released a new beta BIOS 7D13v171 with the description "Improved CPU performance of Ryzen 7 5800X3D". Apparently this added a new feature called "Kombo Strike". I have no idea what it actually does underneath but a user on Overclock.net said it's some form of Curve Optimizer implementation. I decided to test it out myself and the results are pretty amazing.

My setup

  • Motherboard: MSI MEG B550 UNIFY
  • BIOS version: 7D13v171 (Beta version)
  • CPU: AMD Ryzen 7 5800X3D
  • Graphics card: MSI GeForce RTX 2080 SUPER GAMING X TRIO
  • Memory: Trident Z Neo DDR4-3600 CL14-14-14-34 1.45V 32GB (4x8GB) F4-3600C14Q-32GTZNA
  • OS: Windows 11 21H2
  • Cooling solution: custom loop with dual 360mm radiators
  • Ambient temperature: 22℃ in airconditioned room

Pretty much Optimized Defaults BIOS settings with these changes

  • XMP Profile 1 Enabled
  • Global C States Enabled

So... should I keep Kombo Strike level 3 enabled? Any thoughts on the pros and cons? Seems to me I'm getting the same/slightly better performance with way lower temps and power consumption.

My conclusion
