Octane GPU Render Hardware
- Octane render speed (version 3 and 4) directly related to GPU power and count
- octane 3.07 and below don't support RTX 20xx and GTX 16xx GPU,
- octane 3.08 and 4 above support RTX 20xx and GTX 16xx GPU,
- octane 3 and octane 4 use different benchmark points

- Conclusion:
- (3300 SGD budget - 588 @O4) for RTX 2080 or 2080 Ti?
- Go for 2x RTX 2080 Ti, it is better than 3x RTX 2080 setup, 4 PCI-E connection better to manage.
- (2200 SGD budget 621 @04) for 2x RTX 2080 or 3x RTX 2070?
- definitely for 3x RTX 2070, only 3 PCI-E connection to manage and 50% more power.
- (700 SGD budget 209 @O4) RTX 2070 vs GTX 1080 Ti 2nd hand?
- for octane 4, definitely go for RTX 2070, it is better and newer
- for octane 3, you can only go for 1080 Ti
- (700 SGD budget 312 @04 2nd hand) RTX 2070 vs GTX 1070 Ti 2nd hand?
- for price of RTX 2070, you can get 2x GTX 1070 Ti 2nd price.
Final Conclusion
- 2070 and 1070 single 8pin PCI-E power connection is great for multi-GPU and easy Power Supply setup. as even 850W PSU can power 3 of them.
- for 2nd hand price, it is better to buy 3x GTX 1070 Ti at 380×3 = 1140 SGD with 850W PUS (140SGD).
- total = 446 @ O4 score, best for price, only outperformed by 3x GTX1080 Ti (more expensive)
- for brand new card, it is better to buy 3x RTX 2070 at 710×3 = 2130 SGD with 850W PUS (140SGD).
- total = 621 @ O4 score, best for price, only outperformed by 3x 2080 Ti (more than double price.)

Motherboard PCI-E x16 Port Count
- for mATX motherboard, maximum 2 GPU can be plugged. (PCI-E 3.0 x16 + PCI-E 2.0 x4)
- and 2nd slot may block front panel pin connection, so you can use front usb
- example: Asrock B350m Pro4
- for ATX motherboard, maximum 2 GPU for cheap board, and you have free room for front panel pin connection
- example: Asrock B350 Pro4, B450 Pro4
- for better ATX motherboard, maximum 3 GPU can be plugged (PCI-E 3.0 x8 + PCI-E 3.0 x8 + PCI-E 2.0 x4)
- however, some motherboard pin may be blocked by last GPU, but some motherboard has better pin arrangement for this issue
- example:
- Asrock X370 Taichi
- MSI X370/X470 GAMING PLUS AM4
- For 4x GPU or better 3x GPU setup, only high-end CPU board, like X399 series board for AMD TR 2950X can have 4 slot
- some cheap x399 board has 4 slot, but spacing is better which cause only 3 slot can take GPU, like MSI MEG X399 CREATION sTR4
- example:
- ASRock X399 Taichi sTR4, Asrock Fatal1ty X399, 4 Slot with 2 card spacing.
- GIGABYTE X399 AORUS Gaming 7 sTR4 has 5 slot, but only 4 slot can be used to take 2 card spacing
Additional Concern
- some riser card may solve the block pin issue, but not ideal for both case and stability
GPU fan type Blower vs Fan and GPU Size
- for 3 GPU setup or better 2 GPU, those motherboards are better spaced for either fan design type GPU, but of course, Trip fan type are better than blower type in this case
- for 4 GPU setup or those 4 slot motherboard, due to 2 card slot spacing, Blower type is prefered to avoid GPU heat causing clock speed capped.
- Better Casing cooling and Case fan flow control (cleaning and maintain dusts) are always better to keep GPU at high load.
- Those multiple GPU oriented maker all make blower type, like leadtek, zotac, and of course expensive Asus.
- Compare Blower and Fan type extreme case:
GPU if too long, it can also block SATA connectors and USB3 contector in some case
- like leadtek GTX 1070 Ti WindForce is too long in some case and motherboard combination
- some small card like Zotac 1070 Ti mini is small like normal 1060 cards, can fit better in either main slot or last GPU slot without causing pin blocking.
