i7-7700 vs i7-4790K (My Results)

I have retested my main i7-4790K rig @ 4.5 GHz with the PPBM tests, and my results are as follows:

"72","94","25","481", Premiere Version:12.0.1.69

I will be retesting my i7-7700 micro-desktop after updating it, and submit my results in the coming days.

With my i7-7700 on hiatus until I can afford PC Unlocker, I am doing a real-life Cineform HD to DVD SD transcode with a mild application (set at 5.0) of Gaussian Blur. I discovered that my GTX 1060 6 GB was a bit underpowered for my overclocked i7-4790K: In my real-world test, the GPU was constantly pegged at 100% utilization while the CPU bounced between 40% and 60% on all eight threads.

So, if a reference-clocked GTX 1060 was slightly underpowered for a nearly-four-year-old 4-core/eight-thread CPU with a mild overclock applied to that CPU, imagine how much it would bottleneck a newer i7-8700 CPU!

A minor update:

I took the i7-7700 micro-desktop out for a spin. It is being updated, software-wise, as I post.

I will have the results of that system, both with the discrete GTX 1060 and with the integrated HD Graphics 630, shortly.

Uh-oh...

My testing with the iGPU is being delayed for who-knows-how-long. (Intel's drivers for the iGPU do not currently support OpenCL for the HD Graphics 630, but supports OpenCL only with older iGPUs.) I lost my Windows password and my recovery key, and now I cannot access my i7-7700 system now. But before that occurred, I did run preliminary PPBM tests with the GTX 1060 (I cannot access any .speccy or .csv files regarding the results for that system).

My results (preliminary, not submitted) for the i7-7700 are as follows:

"76","95","25","461",Premiere Version:,12.0.1.69

That slower H.264 Blu-ray score compared to my overclocked i7-4790K despite its MPEG-2 DVD score being faster is partly the result of the i7-7700 system having only 16GB of RAM versus 32GB of RAM in my i7-4790K system.

Your H.264 score on your i8-4790K of 94 seconds and the i7-7700 of 95 seconds is not significant remember the Microsoft time stamps are from a 1 second clock. So +/- 1 second change means absolutely nothing.

Thanks for the update, hope you get back in business with your Windows

Randall,

I just entered your overclocked i7-4790K on the CPU page along with a few other entries. You probably need to clear cache on your browser but the new one is dated today. Congratulations you have the best 4-core (8-threads) score to date.

The other scores seem normal but without the Speccy data it is not practical to be any more specific.

Thanks, Bill.

My specific configuration, other than the i7-4790K, was as follows:

RAM: 4 x 8 GB (32 GB total) Crucial Ballistix Sport DDR3-1600 CL9 RAM

GPU: eVGA GeForce GTX 1060 6 GB (non-SC, reference-clocked, not overclocked)

OS Disk: Samsung 850 EVO 250 GB SATA III

Projects / Media / Exports Disk: Samsung 850 PRO 512 GB SATA III

OS: Windows 10 Fall Creators Update 1709

The other new entry that I saw was the 835-second score from an i5-4570. That CPU has only 4 cores and 4 threads, and that score is in line with what I had predicted for that CPU; my now-in-parts-bin i5-6500 averaged a 788-second score in my previous testing.
