Intel’s TDP has long been questioned, but this particular generation put the 95W TDP under fire as users noticed media outlets measuring power consumption at well over 100W on most boards. It isn’t uncommon to see the 9900K at 150W or more in some AVX workloads, like Blender, thus far-and-away exceeding the 95W number. Aside from TDP being an imperfect specification for power, there’s also a lot that isn’t understood about it – including by motherboard manufacturers, apparently. All manufacturers are exceeding Intel guidance for the Turbo boosting duration in some way, which is causing the uncharacteristically high power consumption that produces unfairly advantaged performance results. The other end of this is that the 9900K looks much hotter in some tests.

Be quiet!’s cases are divided into three groups: Dark Base cases are the high-end flagships, Pure Base are (relatively) budget, and Silent Base is the range of cases in between. We’ve most recently covered the Pure Base 600 and the Dark Base Pro 900 at either end of their price spectrum, and now we’re reviewing the Silent Base 601 in the middle.

The be quiet! Silent Base 601 is priced at around $130, depending on when you check retailers, and competes most directly in price with the NZXT H700, Cooler Master H500P Mesh, and Fractal Define R6.

Hardware news coverage has largely followed the RTX 2080 Ti story over the past week, and it's one of dying cards of unknown quantities online. We have been investigating the issue further and have a few leads on what's going on, but are awaiting for some of the dead cards to arrive at our office before proceeding further. We also learned about Pascal stock depletion, something that's been a curious topic when given the slow uptake on RTX.

Further news items include industry discussion on Intel's outsourcing to TSMC, its hiring of former AMD graphics staff, and dealings with 14nm shortages. Only one rumor is present this week, and that's of the nearly confirmed RX 590.

EVGA’s RTX 2070 XC Ultra gave us an opportunity to compare the differences between NVIDIA’s varied RTX 2070 SKUs, including a low-end TU106-400 and a higher-end TU106-400A. The difference between these, we’ve learned, is one of pre-selection for ability to attain higher clocks. The XC Ultra runs significantly higher under Boost behavior than the 2070 Black does, which means that there’s now more to consider in the $70 price gap between the cards than just the cooler. This appears to be one of the tools available to board partners so that they can reach the $500 MSRP floor, but there is a performance cost as a result. With Pascal, the performance cost effectively boiled-down to one predicated on thermal and power headroom, but not necessarily chip quality. Turing is different, and chip quality is now a potential limiter.

In this review of the EVGA RTX 2070 XC Ultra, we’ll also be discussing performance variability between the two 2070 GPU SKUs. These theories should extrapolate out to other NVIDIA cards with these sub-GPU options. Note that we are just going to focus on the 2070s today. If you want to see how we compare the 2070’s value versus Vega or Pascal, check our 2070 review and Vega 56 power mod content pieces.

The real discussion is going to be in overclocking and thermals, as gaming performance typically isn’t too varied intra-GPU. That said, the GPU changes between these two (technically), so that’ll make for an interesting data point.

We previously deep-dived on MCE (Multi-Core Enhancement) practices with the 8700K, revealing the performance variance that can occur when motherboard makers “cheat” results by boosting CPUs out of spec. MCE has become less of a problem with Z390 – namely because it is now disabled by default on all boards we’ve tested – but boosted BCLKs are the new issue.

If you think Cinebench is a reliable benchmark, we’ve got a histogram of all of our test results for the Intel i9-9900K at presumably stock settings:

1 z390 motherboard differences cinebench histogram

(Yes, the scale starts at non-0 -- given a range of results of 1976 to 2300, we had to zoom-in on the axis for a better histogram view)

The scale is shrunken and non-0 as the results are so tightly clustered, but you can still see that we’re ranging from 1970 cb marks to 2300 cb marks, which is a massive range. That’s the difference between a heavily overclocked R7 2700 and an overclocked 7900X, except this is all on a single CPU. The only difference is that we used 5 different motherboards for these tests, along with a mix of auto, XMP, and MCE settings. The discussion today focuses on when it is considered “cheating” to modify CPU settings via BIOS without the user’s awareness of those changes. The most common change is to the base clock, where BIOS might report a value of 100.00, but actually produce a value of 100.8 or 100.9 on the CPU. This functionally pre-overclocks it, but does so in a way that is hard for most users to ever notice.

The Cooler Master SL600M was one of the most promising cases we saw at Computex 2018, using CM’s now-familiar 200mm fans in a bottom-to-top airflow configuration. Although the “chimney effect” and “stack effect” are genuine insofar as their physical existence, the usefulness of natural convection processes fades when confronted with high CFM, directional fans. Hot air does rise, of course, but air blasted through a fan goes wherever you want it. In this regard, we are not firm believers in the “chimney effect” as a marketing characteristic for computer cases -- not unless those are passively cooled, anyway -- even still, the last case we tested with a similar configuration was the RV02, which remains one of the best cases we’ve tested thermally.

These improvements are for other reasons, not because the heat is rising. It’s because the air path is superior, and placing several large fans at the bottom of a case (given sufficient distance from the table) can cool parts faster. The path to the GPU is shorter, and so cooler air is hitting the video card fans faster.

Cooler Master’s SL600M ends up at around $200, and enters a market with more competitors at its price class than is typical: The NZXT H700i, Cooler Master’s own H500M (or H500P Mesh), and the Phanteks Evolv X are all relatively recent contenders in this arena.

Today, we’re reviewing the Cooler Master SL600M for thermals, acoustics, build quality, and value.

Intel broke silence this week in response to media reports that its 10nm process "died," denying the claims outright and reaffirming target delivery for 2019. This follows reports emboldened by Semiaccurate of the discontinuation of the current 10nm process development, a site that previously accurately predicted issues with 10nm production. We've also seen plenty of AMD news items this week, including a slumped earnings report, Vega 20 rumors, and RX 590 rumors.

The shows notes are below the video, as always, for those favoring reading.

We’re resurrecting our AMD RX Vega 56 powerplay tables mod to challenge the RTX 2070, a card that competes in an entirely different price class. It’s a lightweight versus heavyweight boxing match, except the lightweight has a gun.

For our Vega 56 card, priced at between $370 and $400, depending on sales, we will be shoving an extra 200W+ of power into the core to attempt to match the RTX 2070’s stock performance. We strongly praised Vega 56 at launch for its easily modded nature, but the card has faced fierce competition from the 1070 Ti and 1070. It was also constantly out of stock or massively overpriced throughout the mining boom, which acted as a death knell for Vega throughout the mining months. With that now dying down and Vega becoming available for normal people again, pricing is competitive and compelling, and nVidia’s own recent fumbles have created an opening in the market.

We will be working with a PowerColor RX Vega 56 Red Dragon card, a 242% power target, and matching it versus an EVGA RTX 2070 Black. The price difference is about $370-$400 vs. $500-$550, depending on where you buy your parts. We are using registry entries to trick the Vega 56 card into a power limit that exceeds the stock maximum of +50%, allowing us to go to +242%. This was done with the help of Buildzoid last year.

One final note: We must warn that we aren’t sure of the long-term impact of running Vega 56 with this much power going through it. If you want to do this yourself, be advised that long-term damage is a possibility for which we cannot account.

After our launch-day investigation into delidding the 9900K and finding its shortcomings, we’ve been working on a follow-up involving lapping the inside of the IHS and applying liquid metal to close the story on improvement potential with the delid process. We’re also returning to bring everyone back to reality on delidding the 9900K, because it’s not as easy as it may look from what you’re seeing online.

We already know that it’s possible to see performance improvement, based on our previous content and Roman’s own testing, but we’ve also said that Intel’s solder is an improvement over its previous Dow Corning paste. Considering that, in our testing, high-end Hydronaut paste performs nearing the solder, that’s good news when compared to the older thermal compound. Intel also needed to make that change for more thermal headroom, so everyone benefits – but it is possible to outperform it.

Hardware news for the last week has primarily revolved around re-re-releases of hardware, like NVIDIA's GTX 1060 GDDR5X model and AMD's RX 580-not-580. Both are unimaginative, but worth covering. For its part, AMD's RX 580 is an RX 570, just 40MHz faster. It has the same FPU count as the RX 570, despite being named "RX 580." NVIDIA's launch, meanwhile, is a move from 8Gbps GDDR5 to GDDR5X on the 1060 6GB card, which has previously already been pseudo-re-released as a 3GB model and (now gone) 9Gbps model.

Other hardware news includes reduced RAM pricing, SSD pricing, and more. The show notes are below the embedded video, if you prefer articles.
