* 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 380x3 = 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 710x3 = 2130 SGD with 850W PUS (140SGD). * total = 621 @ O4 score, best for price, only outperformed by 3x 2080 Ti (more than double price.) ===== Power Supply Connection Consideration ===== | PSU (Seasonic) | Connector | cost2022 | | gm750W | | 150 | | s12iii 650w | | 93 | | PSU (Seasonic) | Connector | cost2019 | | S12II 520W | 2 PCI-E max | 75 | | S12II 620W | 2 PCI-E max | 91 | | M12II 850W | 3 PCI-E max | 140 | | PrimeUltra1000GD | 4 PCI-E | 240 | | Prime 1300GD | 6 PCI-E | 293 | ===== 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 * http://tomglimps.com/custom-pc-for-otoys-octane-render-by-polder-animation/ ===== 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: * https://www.pugetsystems.com/labs/articles/GeForce-RTX-2080-Multi-GPU-Scaling-in-OctaneRender-and-Redshift-1258/ **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. ===== Reference ===== * Octane Benchmark * octane 3.08, RTX vs GTX: https://www.pugetsystems.com/recommended/Recommended-Systems-for-OTOY-OctaneRender-192/Hardware-Recommendations * Octanebench 4 for RTX and GTX: * https://render.otoy.com/octanebench/results.php?v=4.00&sort_by=avg&filter=&singleGPU=0 * Octanebech 3.06 for GTX: * https://render.otoy.com/octanebench/results.php?v=3.06.2&sort_by=avg&filter=&singleGPU=0 * Mix GPU render result: * https://www.pugetsystems.com/labs/articles/Can-You-Mix-Different-GPUs-in-Octane-and-Redshift-1189/ * RTX GPU vs GTX GPU in 3.08 * https://www.pugetsystems.com/labs/articles/OctaneRender-3-08-NVIDIA-GeForce-RTX-2080-2080-Ti-GPU-Rendering-Performance-1241/ * Calculation * Power calculator: http://www.coolermaster.com/power-supply-calculator/ * Price to Power table: https://www.videocardbenchmark.net/gpu_value.html * Build Guide * https://renderstorm.com/2018/03/best-hardware-gpu-rendering/ * https://www.cgdirector.com/best-computer-3d-modeling-rendering/ * https://www.cgdirector.com/best-hardware-for-gpu-rendering-in-octane-redshift-vray/ * https://help.otoy.com/hc/en-us/articles/214357103-Hardware-Suggestions
