A Hong Kong-based PC expertise and opinions website has found {that a} sanctions-compliant Asus ROG Strix GeForce RTX 4090D graphics card will be overclocked to “obtain the performance stage of the RTX 4090 FE.” HKEPC obtained certainly one of Asus’ finest graphics playing cards within the labs for testing and ran a mess of artificial and gaming benchmarks, pitting the RTX 4090D towards a handful of its extra acquainted GeForce siblings, together with the RTX 4090. It additionally had no bother overclocking the US sanctions-compliant graphics card utilizing GPU Tweak III, which then boosted performance to the extent of a standard RTX 4090.The RTX 4090D is a cut-down model of the top-end client graphics card from Nvidia, designed to limbo underneath particular performance metrics laid out by the US authorities. These sanctions are meant to deny China entry to superior chips that could possibly be used to improve its army prowess. The distinction between the Nvidia GeForce RTX 4090 and RTX 4090D has been properly documented in our earlier articles, as have the explanations behind the existence of the latter.Swipe to scroll horizontallyRTX 4090D SpecificationsRow 0 – Cell 0 RTX 4090DRTX 4090SMs114128CUDA Cores14,59216,384Tensor Cores456512RT Cores114128Boost Clock2,520MHz2,520MHzBase Clock2,280MHz2,235MHzVRAM Speed21Gbps21GbpsVRAM Capacity24GB GDDR6X24GB GDDR6XVRAM Bus Width384-bit384-bitVRAM Bandwidth1,008GB/s1,008GB/sL2 Cache72MB72MBROPs176176TMUs456512TDP425W450WTo make a sanctions-compliant model of the GeForce RTX 4090, some key GPU tech specs had been minimize. For instance, the AD102 die frequent to the RTX 4090 and 4090D has fewer CUDA cores and RT cores, slower clocks, and a TDP cap on the sanctions-compliant mannequin for the Chinese market. Nvidia’s shrewd snips edged the RTX 4090D underneath a TPP (Total Processing Power) determine set at 4,800, whereas the RTX 4090 has a TPP of round 5,286 for FP8 work operating on the Tensor cores.We have seen opinions of the RTX 4090D beforehand, suggesting that the Chinese market-targeted card is solely about 5% slower in gaming, and 10% slower in AI workloads (Galax mannequin) than the full-fat RTX 4090. However, HKEPC appears to have managed to do higher than its China rivals utilizing the Asus ROG Strix GeForce RTX 4090D. The very first thing it seen was that this card was “precisely the identical” because the sanctioned RTX 4090 model, besides for the cut-down AD102-250 GPU core getting used, with the good cooling and superior options remaining intact.An intensive vary of artificial and gaming exams had been accomplished with the RTX 4090D at inventory settings, making up a lot of the HKEPC article. The Asus carried out as anticipated right here, nestling between the RTX 4080 and RTX 4090, however often residing nearer to the flagship.Overclocking the ROG Strix GeForce RTX 4090DHKEPC noticed that the ROG Strix RTX 4090D model “has lifted the restriction of not having the ability to overclock, and the TGP energy consumption will be liberated.” Apologies for that machine translation, nevertheless it additionally particularly mentions that Asus GPU Tweak III may elevate the ability restrict to a most of 600W. Its finest overclocking tweaks ended up being: GPU Clock +200 MHz, Mem Clock +187 MHz, nevertheless it consumed up to 558.4W with these settings. The consequence was that HKEPC efficiently boosted the Speedway benchmark scores from 9,894 to 10,818, representing a 9.3% uplift. Testing in 3DMark Port Royale delivered the same story, with an uplift of 8.7%.Join the consultants who learn Tom’s Hardware for the within observe on fanatic PC tech information — and have for over 25 years.

Last however not least, the Hong Kongers reckon that the low-hype RTX 4090D is a fairly whole lot however fear that when the RTX 50-series arrives, China residents gained’t even give you the option to purchase the ’80.’
