Topic: Benchmark not showing good specs

[carlsunder]

Hello,

We are a high school looking to update our machines that run Lumion. Currently on v 5.7.2.  When running the benchmark on our current machine, we get the results shown in the attachment "Current Machine".  When we run it on the new machine we are considering, we get the "New machine" attachment.

We know the graphics card needs to be changed in the new machine, that is not the issue.  My question is why is the CPU scoring so poorly on the new machine?  The new CPU is the AMD PRO A8-8650B, which gets a Passmark score of 5431 on their site, but here it's only scoring 1350 in the Lumion benchmark test.  Am I missing something simple?  Thank you!

Hi carlsunder

It does seem confusing especially as the AMD is a recent CPU release  .

However the CPU is really only a four core CPU, as is the i5-2500.  The 10 compute cores as I read it is made up of 4 CPU cores and 6 integrated graphics cores based on the R7 (Radeon 7).

The i5-2500 has a better Passmark, 6227 compared to the AMD of 5431 so that's an immediate difference of 15%.

Lumion requires at minimum a CPU with 6000 Passmarks, refer LUMION 5: Minimum hardware requirements.  So the CPU in the new PC's are actually a backward step in terms of meeting requirements for Lumion.

I can't tell what the clock rate is of the AMD, but the product comes in either 3.2 or 3.9 for desktops.  So if it's a 3.2 clock then again that's slower than the i5.

The AMD CPU on that information would simply not allow Lumion to work well at all.   

You would need to ask your technical support to also test with a dedicated GPU that meets Lumion requirements.

Thank you for the reply.  You've confirmed my suspicions.  Thank you!
