Core 2 Duo Games Without Graphics Card

[Mandy Geise]

Hello, I have a core i7 6700k on a MB Gigabyte GA-Z170X-Gaming 7..I have a weird problem :If I don't put a graphic card on the pci slot, the computer won't boot ... there is a beginning of boot, sometimes going until W10 " automatic repair", but it stops and restarts infinitely.

I plan on building a full enclosure for my cnc machine pretty soon, and I am considering building the computer for code-sending into the enclosure. I happen to have a very old quad-core cpu, mobo, 8gb of ddr2 ram, and power supply lying around that I would like to use, if possible.

Currently, Fusion runs OK on my laptop, which has an old i5 and 8gb of DDR3. The ram usage never goes above 50%, but the CPU usage is generally quite high. This old i5 has 2 physical cores with 4 threads. Not sure if that is very different from the old quad core with 4 physical cores. The only thing I don't like is that generating toolpaths takes a very long time on the laptop.

You'll need a GPU to run Fusion 360. If you curious how it might look, you could try disabling your graphics cards in the device manager on an existing Windows machine. I don't believe Fusion 360 will run well without a graphics card. It will be slow and unstable, if it runs at all.

For example, for drawing a single very CPU-intensive plot or solving a very CPU-intensive equation, would upgrading the graphics hardware result in speed-up? Would upgrading to a CPU with more cores speed things up? (I realize that more cores mean I could solve more equations in parallel but I'm curious about the single-equation case)

I wouldn't say Mathematica does automatically GPU or Paralell-CPU computing, at least in general. Since you need do something with paralell kernels, then you should initialize more kernels and/or upload CUDALink or OpenCLLink and use specific Mathematica functionality to exploit the potential of CPU and/or GPU.

If you don't parallelize explicitly, I believe there are still certain numerical calculations that take advantage of multiple cores. I'm not sure which one, but I do know that some linear algebra related functions (LinearSolve, Det, etc.) use multiple cores by default.

I disabled the integrated graphics. So does the processor use those 6 GPU cores for anything? I found this, but the comments there are more for intel chip. And they are arguing over whether the CPU cores perform better after adding a dedicated graphics card, not really addressing what happens to the GPUs. The consensus seems to be a faster CPU without the heat generated from GPU and better performance without sharing RAM with GPU. This implies the GPUs are sitting idle, but I am not sure if that's the case, and whether it holds for both Intel and AMD.

(What I would like to hear is that these cores are available. Part of the reason I built this rig was to be able to run several million statistical simulations. That would be helped considerably by being able to run 6 or 8 cores at a time in parallel, instead of just 2 or 3.)

I didn't read the link you have, but I disagree with those saying the CPU cores performance is affected whether you have a integrated or dedicated GPU. The only case in where integrated graphics may affect the CPU is when you have single channel system memory, because it would create a bottleneck. An integrated graphics card is either built onto the motherboard, or is built into the die of the CPU. Although they may be housed on the same die, they each have their own separate processing capabilities, because the graphics controller is separate from the CPU.

The biggest difference between a dedicated GPU and an integrated GPU is the memory it allocates. An integrated GPU uses some of your system memory (RAM), rather than having it's own dedicated memory. A discrete graphics card has a GPU and it's own set of VRAM, rather than using the system RAM. The RAM on your graphics card is also much faster than system RAM.

Your question about using the integrated GPU cores as CPU cores, the answer would be no. These cores are designed differently than CPU cores. It could be possible that some programs can use GPU cores, like mining for bitcoins. But those programs are specifically made to run like that.

If, however, you do want to take advantage of these GPU cores within a gaming workload, AMD Dual Graphics allows you to use the GPU cores on your APU in Crossfire with certain AMD cards. According to the product page, AMD recommends pairing with an R7 240 if this is a path you want to go down.

I am more knowledgeable of NVidia than AMD, but I believe this answer would apply to AMD as well. Assuming you bought a card from the past couple years, and that it cost more than $25 then you should have massively more GPGPU power available to you than you do in a combo ADM CPU/GPU like the AMD A8 (having owned an A8 & A10 I can safely tell you that).

As DrZoo points out regarding the memory use and architecture of the A8 compared to the discreet card, when it comes to actually coding the simulations you want to do, you will learn how the GPU itself is comprised of memory levels similar to the CPU (L1,L2, L3) and that this memory can be used wisely to be shared between GPU Blocks and Threads, or between Host & Device (CPU & GPU) and also static memory for unchanging data like a value used in your statistical models that must be used in all your calculations. In this case the static memory will only cost you one memory read, and even if your calculation needs that value millions of times it still only needs to go into memory once to retrieve it.

Once you get into the architecture of today's video cards (again, only knowledgeable of NVidia) you will discover that you have access to supercomputing type powers of massively parallel processing that you could never do in an AMD A8 chip. You will realize thoughts of whether the GPU cores are sitting idle of disabled no longer matter, as your $100 video card (or $700 NVidia GTX 1080 in my case) is so substantially more powerful it is meaningless to worry about those cores.

Graphics card requirements for Enscape are serious. It is a bit beyond my ken. Who is going to make this easy for me? I have AMD 15DD Graphics card and Enscape says it's out of date. Trying to use the graphics card update Enscape recommmends for 3.2.0 didn't work either, I guess because my existing graphics card is so meager. But my computer guy says what I need is simply a bigger video card, because mine only has 1 GB ram (or vram?), and that is what he plans to get for me. But he says it's takes a long time to get video cards because everything is slowed down because of pandemic. Reading these comments here and anywhere about graphics card requirements for Enscape is like reading Greek. Have never had to get this involved in graphics cards. Takes a certain level of expertise. Wish Enscape could make it easier. I have HP desktop and windows 10.

Indeed, if your graphics card only has 1GB of VRAM (Graphics card memory), then you will not be able to run Enscape - You will have to acquire a GPU with at least 4GB of VRAM, ideally more. I also understand the situation is dire lately when it comes to more modern GPUs which cannot be acquired at the moment, or only for insane prices.

Besides that, if the GPU is suitable for Enscape, most of the time the rest of your machine would suffice, especially if you're able to use Revit, SketchUp, Rhino or ArchiCAD without Enscape, without any performance problems.

In this case, I recommend you further refer to your system admin, to perhaps look for a good deal on a used GPU, or you're going to be lucky and get one new for a decent price. Which may be unlikely for a couple more months at least.

The previous generation is the 20 series, I have a 2070 that has 8Gb of vram and its working well for my needs, you/your computer guy could look for a second hand 20 series though as Demian pointed out the market is nasty at the moment with ridiculous prices for anything out there.

I had no idea it (Enscape) would be this difficult and expensive! I don't know anything about graphics cards, even though I'm quite proficient with SketchUp, Vray and Corona Render (which I use with Cinema4D and SketchUp). This is a whole new thing. I used all of those programs on my two or three year old HP Pavillion Desktop 590-P0024 computer (with the AMD15DD graphics card) with no problem except I added some ram. I don't even know what to shop for. What would I be shopping for? How would I describe what I need? Thank you.

I have another question. Is there a chance, if I do get the proper graphics card, that I will be able to run Enscape on my 2017 version of Sketchup? Your specifications say only 2018 and up (but I guess you mean Sketchup Pro; don't think they refer to their versions with year numbers anymore) but when I tried to open my trial Enscape plug in, the only message was about my graphics card, so I was hoping maybe it would work in my 2017 version. Thank you.

It really only is difficult and complicated at first - Once you've wrapped your head around the current GPU models available, there really are not that many which we would really recommend. You can of course also always refer to our system requirements just to see which GPU's we list. I'm not sure what you mean by "what would I be shopping for", are you referring to the GPU now or other PC components? This is also usually where the system administrator comes into play which should be able to clear a few things up and give you perhaps a brief introduction into which PC components are important for 3D rendering (Which Enscape does) and such, but any further questions can also be directed at me/us of course!
