and please do a verification @baseclock if intel holds its 95W TDP
Highly questionable if you ask me.
Though, even if it
won't exceed those 95W for base clocks, it will pull pretty exactly
+230–250W at the wall, excluding the rest of the system –
at stock clocks under full load. Mind
any overclocking!
Anyway, the overall power-consumption will bump quite a bit! It's still physics, isn't it?
The power-draw can be extrapolated quite easily, ordinary rule of three …
Gaming Load
If a
8700K needs about 66.8 Watts with its 6 cores on a average gaming-load, then a
9900K will be drawing about 89.07 Watts. Still, it won't run on its stock-clocks of 5 Ghz but 'only' on a
8700K's 4.7 GHz – so you have to add the additional consumption which even comes on top of that.
Calculation:
Averaged power-draw at stock-clocks (@4.7 GHz)
Average gaming-load OC'd (@4,9 GHz)
… which makes it ~90W on average gaming-load @4.7 GHz on 8 cores, just by the numbers alone.
So a
9900K will be consume
at least 90W (in the best theoretical case) – though, this
will not be the actual case since it has a 33% increased Cache compared to the
8700K (12 vs 16 MByte). So due to that fact (of the increased Cache) alone it will be drawing significant more power than those 90W and probably will exceed the TDP of 95W.
Or in other words, it will be very likely that the
9900K will already exceed its TDP of 95W already at stock clocks (as you can see by the already overstepping 95.74 Watts at 4.9 Ghz), especially if it runs
any warmer.
Full load
If we then have another look on the
8700K while being under heavy torture load like Prime, we see it doesn't get any better anyway. At Prime a
8700K pulls already 159.5 Watts@stock – and as such, a
9900K will be pulling also at least 212.67 Watts. Having said this, it's still ain't running at its stock-clocks at 5 Ghz but again still 'only' at stock-clocks of a
8700K at 4.7 Ghz. … of course without the additional power-draw of the remaining +300 Mhz, sans the increased power-consumption of its larger cache.
Calculation:
Full-load power-consumption at stock-clocks (@4.7 GHz)
Full-load power-consumption OC'd (@4,9 GHz)
As a result, a
9900K will be in that (still best theoretical) case consume
at least circa
212.67 W under full load – admittedly, even that won't be the actual case as it still has a 33% increased Cache compared to the
8700K (12 vs 16 MByte). Hence, due to that fact of its increased Cache it will be consume significantly more. On average the
9900K might be easily draw
+230–250 Watts. In any case, the official fantasy-TDP of just 95W is here pure maculation and by all means just printer's waste. So, as usual on Intel's official extremely misleading TDP-specifications.
Final conclusion
Note!
All numbers here are always representing the
best case (sic!) and are in fact
the best possible and assumable Numbers, since we're still at 4.9 Ghz in this scenario. Any greater attention should also be paid to the evident fact that
in every single case and all numbers do reflecting the actual Package Power Consumption and as such those are solely reflecting only the processor's consumption
in and of itself.
Those numbers ain't the power consumptions of the whole system! Those are the
CPU's values alone.
☞ Please also note, that the Cache which now has a Size increased by 33% will be making
significant contributions to actual Wattage-numbers. Furthermore, all numbers arose with the assistance of a Chiller which cooling loop was cooled down and held permanently at 20°C (which, as a side-note, didn't even could hinder the
8700K from running into its thermal limit).
Résumé or bottom line
- All of those are Best case-values.
- All Wattages and (possible) clock frequencies under utilisation and made possible through the use of a Chiller (Compressor-cooling).
- All calculations lacking the remaining clock speed of +100 MHz towards the nominal-clock of the 9900K (naturally including the respective overconsumption)
- The actual Wattage might be very likely levelling off at +230–250 Watt nominal-consumption, at stock-clocks under full load.
