I got disappointed with the Results of Unigine 4 benchmarkings of my new PC (compared with old PC)...
Can anyone please explain

For both the setups, I used same Unigine settings
Setup1(Old): Min Frames:3, Max Frames:16
Setup2(New): Min Frames:2, Max Frames: 13.2

Why the new setup is giving less frames ...


Setup1:
CPU: AMD Phenom II x2 550
RAM: Dolgix 8GB (4+4 GB) 1333
Graphics: Radeon 4650 with 256MB GDDR4
MotherBoard: Biostar T890GX


Setup2:
CPU: Intel i7 4790
RAM: Corsair 8Gb single stick 1600
Graphics: Radeon 4650 with 256MB GDDR4
MotherBoard: MSI Z97 PC Mate

(I have used same display card in both the setups)

I doubted on i7 CPU, so performed health test with software from Intel's own website, CPU passed
 


Temperature of i7 was in between 50-60 but GPU temperature was peaked till 65 deg

I have changed the RAM from 1333 Dolgix to Corsair 8GB 1600 but there is almost no change in the results

One more information I missed

During test i7 utilization was in between 10-20 only ... where as the Phenom 550 utilization was around 50-60% ... CPu is not bottlenecked and GPU is same in both the setups, but why new setup is behind
 


Dunno? Dual channel memory, maybe?
 
I want to share what made me to get new PC ... I brought Zotac GTX 970 Omega Graphics card and fixed on my old PC ...
->It worked fine for one Hour...
->And after My PC got switched off suddenly ...
-> I suspected PSU, and finally it is fine
-> Figured it out that Graphics card died but along with this it took away my X-Fi Xtreme Gamer Sound card. So Sound card and Graphics card got died together

I switched to Intel i7 PC ... I expected more with i7 but all are collapsed with the unigine benchmark results ...

Asus Strix GTX 970 on the way ... before that I want to know why i7 performing poor

(My OLD Phenom 555 PC With Zotac GTX 970 Gave Min FPS: 18 Max FPS: 45+ with all Maximum settings but card died in an hour)



 

If Dual channel is the issue, why i7 is giving same results with Single Corsair 1600 8GB vs two Dolgix 1333 4+4GB
 


There won't be much difference anyway, since the intel is running at 1600 (but single channel) and the AMD was 1333 but dual channel,.

 


There is almost same FPS with the Setup --- i7 with Dual Channel vs Single channel
 


I doubted here on CPU ,if I test for GPU, I do not think it will be helpful ... anyways my GPU is getting replaced with GTX 970 Strix ... I want to make sure that mobo+cpu are not defective

 

dude, you`re testing a 256 MB video card on modern titles ... i`m amazed that the damn thing even got the game running ... I play Battlefield 4 and i get 2.3 GB of video ram usage, you have 256 MB .. that`s 0.2 GB of ram.
 


You are correct ... I should not use 256 MB GPU with modern setup ... fact is GTX 970 on the way, in the mean time, I fixed this old GPU to new setup (it will sit till my gtx 970 comes) ... Just I am interested to know the reason why new Setup with Old GPU is performing worse than New Setup with Old GPU ... AND ... to make sure that my new hardware is not defective
 


I am more concerned regarding your hardware losses, I have never heard of a GPU failure taking a Sound Card with it?

That is more of a Power Supply failure taking multiple hardware components?

->It worked fine for one Hour...
->And after My PC got switched off suddenly ...
-> I suspected PSU, and finally it is fine

Are you absolutely positive the Power Supply is OK?

Did you use a multi-meter and check the power supply voltage output?

How do you know, that those failures have not damaged the motherboard?

I would want to be 100% sure before I plugged in your RMA'd GPU.

 


 
Keeping all aside ... can anyone of you people tell me (if you know) ... What is the Unigine benchmark result with the Combination i7 4790 + MSI Z97 PC MATE when built-in graphics used (regardless to the RAM) so that I can compare the result straight away and figure it out what is wrong with my hardware
 


Onboard graphics is very poor compared with my Old Radeon, ... If I use Onboard Graphics and run Unigine, it will be almost like system freeze and even not able to move mouse curser to Benchmark button
 


Please see the unigine heaven ultra settings comparison and let me know if you could justify why i7 is lagging

Your GPU is bottlenecking your CPU. Your new CPU needs a better Graphics card to truly show its superior potential benchmarking in Unigine. Once you change your GPU try running the benchmark again. As the above mentioned, make sure you test your PSU, I would be concerned having another component die if your power supply is having problems.
 
Just update your bios of the motherboard to version 4.A
You can find it on the msi website

Did you do a fresh install of windows? After upgrading the hardware? If not, that's the problem.
After fresh installing windows, install the drivers from the Intel website, Z97 chipset and Intel HD graphics drivers.

Which power supply is it exactly ?
 



May be you are correct ... Fresh Windows installation not done
(Why I could not do Fresh installation because, Disk is in MBR but Installation require GPT style disk, I cannot change to GPT as my disk contain so much of important data ... after data backup ... I will try fresh and redo the test and let you know the result)

Drivers installed from MOBO DVD ... not from the Intel website
PowerSupply Corsair VS550

it seems you are close to the solution
 


Are you crazy the HD Graphics 4600 is better than that outdated GPU
