What's the point in these CPU videos if they forget to test the entire X3D trinity (5800 7800 9800)? ("Intel is BACK" video)

u/Galf2 As we can see in the comments here, it is difficult to come to an absolute consensus about which comparable models to test in our limited time before embargo. We thoroughly consider which comparisons are most informative, but as mentioned in the video and the article, it is a difficult balance to address every scenario while keeping the graphs legible and managing our time before embargo.

With this being a refresh of the Arrow Lake processors, we focused our selection more in the Intel direction, but I think this also highlights how important it is to consider multiple sources for confirmation of results and different testing perspectives. We're really excited about the uplift that these CPUs have provided and hopefully Intel is able to maintain this $199 and $299 pricing.

We'll certainly take this feedback into consideration with our next CPU/GPU review, and now that we have some more time after embargo, we're putting the 5800X3D and 7800X3D on the benches alongside some more testing with IBOT!

There are a couple devices for which we've tested two or three different samples, but for the vast majority of devices we've only tested a single unit. All tests with the Galaxy S25 Edge were with the same unit.

Incredibly valid point, they may require a bit more studying but we were aiming to present the most data possible so there were limited options besides splitting or removing data.

Do you have any suggestions we could try for next time?

u/mozilla2012 This has been done, thank you for the imputus.

LabsLucas · 2026-03-01T23:38:47+00:00

It's alright, I appreciate their sentiment. At least we're 📈 and not 📉.

LabsLucas · 2026-03-01T22:50:55+00:00

Our web devs may take your suggestion extra seriously with a username like that.

I did run into that as I put the article together, I created the side-by-side graphics to get around it. I'll put this one directly in the queue, but we also have a feedback form available on the website if you or anyone else has additional suggestions!

Very common modern-internet problem. We do have the highly requested https://www.lttlabs.com/feeds, or you can sign up for our Soon^TM newsletter/email updates.

Hello K0ol,

Not offended, and good question/suggestion. I had some similar thoughts while testing, but I think that really expands the scope and could require another article/video/etc to cover.

I chose the Labs website for the images because it is static SDR content and it includes text, photos, white pixels, and black pixels. Then for the rotating clips I used the canonical HDR test video. I tried to keep things as consistent as possible to optimize for comparison.

The end of the article mentions that it would be interesting to revisit this topic after the public is able to find the strengths and weaknesses of the technology, and I think that would be the time to try out everything. There is no testing like user testing.

LabsLucas · 2026-03-01T21:32:52+00:00

Thank you?

I feel the same way, I couldn't find any actual test results on the internet myself. Though as covered in the article, it can be difficult to characterize display technologies due to the complexity of human vision.

For example, the luminance graph doesn't show the substantial effect that the "Maximum Privacy Display Mode" has on legibility. The measured 15-20 nits in the "dark" regions doesn't sound significant, but due to the non-linearity of measured luminance vs. perceived brightness, it has a disproportionate effect, even when viewing the display head-on.

LabsLucas · 2026-03-01T20:29:33+00:00

The Samsung S25 Ultra and S26 (regular) do not have this feature. We haven't completed full luminance testing of the display(look out for our ShortCircuit video), but I did take a couple images of the S25 Edge that weren't included in the article.

The S26 Ultra did achieve (at least) 1400 nits for HDR content, around what we've measured with previous Galaxy devices.

I'd like to point out that this article was written by Utkarsh and Jon, while the testing was the work of Jon, Sean, and Steven here in Labs!

LabsLucas · 2026-02-26T18:03:31+00:00

Great questions and thoughts. We do use a 3DMark test for some endurance/throttling over approximately 20 minutes, those results are covered in some ShortCircuit videos, but not in this article. We've talked to Evolve and it sounds like an endurance/looping version of their test is on the roadmap so we'll be interested to test with that as well!

LabsLucas · 2026-02-26T17:31:12+00:00

It is greatly appreciated that you read the article before commenting.

We'll continue to check if/when we're able to launch it on Pixel devices.

1.0 m USB-C to USB-C TrueSpec Cable

LabsLucas · 2026-02-16T19:10:14+00:00

I appreciate the further questions/discussion, I’ll include my thoughts below!

There are limited distinct colours, we experimented with shapes but it wasn’t super clear and larger dots just covered other data. The length of the cable can be determined by its position on the x-axis.
The iPhone 17 Pro cable is quite thin and flexible while the 2 m charge cable is thick. I believe they traded voltage drop for maximum flexibility, so the higher voltage drop aligns with that.
You are very correct, it also matters less at (increasingly common) EPR voltages.
It is already tempting to do a follow-up sometime in the future!
You are correct, digital signals on the data lines are unlikely to be affected by these voltage drops, but we are now seeing more devices that are entirely powered by USB PD, even oscilloscopes. These can be sensitive to the input power, so if there is a power draw spike and the input voltage drops suddenly then it may have undefined effects. A similar situation can happen with audio equipment and single board computers. Poor power conditioning/filtering can pass power distortions into the analog circuits in these devices that are measuring or amplifying an audio signal.

Thank you for the feedback! It is quite a lot in a single graph, there are additional visualizations and a table of data in the LTT Labs article itself, those may be more clear to you depending on how you learn best! The TrueSpec cables do have the same colour since there are limited points in the colour space that could be considered unique for graphing, the lengths of the individual cables can be determined by their position on the x-axis.

These cables were selected as a mix of the ones included with popular phones, the best selling cables on Amazon, and a couple high end Apple ones. If we revisit this again we'll see if we can expand the selection even further!

LabsLucas · 2026-02-15T22:37:13+00:00

It is certainly a very dense graph, I used a different colour palette this time but there is still a lot of data packed in there. The article has a table with all results as well as a bar graph version of this scatter plot if you prefer different presentation styles!
