NVIDIA unveiled the GeForce GTX TITAN-X at the Game Developers Conference (GDC) 2015. Sadly, there's nothing you can compare that score with. With four of these cards in play, you get X24064 points. The card scored X7994 points going solo - comparable to Radeon R9 290X 2-way CrossFire, and a single GeForce GTX TITAN-Z. Someone with access the four of these cards installed them on a system driven by a Core i7-5960X eight-core processor, and compared its single-GPU and 4-way SLI performance on 3DMark 11, with its "extreme" (X) preset. Here are some of the first purported benchmarks of NVIDIA's upcoming flagship graphics card, the GeForce GTX TITAN-X. It could fall into the same gray area that allows EVGA to sell its HydroCopper variants.
NVIDIA restricts its add-in card partners from coming up with custom-design cards, but this mod appears to be by an OEM, and these cards won't be sold in the retail channel. Given that the GPU will run cool, we imagine that the blower will not be as noisy. The memory and VRM is cooled by a base-plate that's ventilated by the NVTTM (NVIDIA time-to-market) reference cooler's main blower. The loop itself appears to be basic Asetek fare, with a round pump-block cooling the GPU, with its heat being dissipated by a 120 mm x 120 mm radiator.
Found on the company's G-Master Hydro series gaming desktops, these modified GTX TITAN X cards look reference, except a cut-out on its top, through which coolant tubes pass through.
Japanese OEM gaming PC builder Sycom addressed the biggest shortcoming of reference NVIDIA GeForce GTX TITAN X - heat (which runs into a thermal throttle too often), and the resulting noise (rivaling that of a Radeon R9 290X reference), by innovating a new all-in-one liquid cooling solution. The core clock speed on the R9 390X is 1050 MHz (up from 1000 MHz on R9 290X) and 1000 MHz on the R9 390 (up from 947 MHz on the R9 290). The memory clock has been increased from 1250 MHz (5.00 GHz GDDR5-effective), to 1500 MHz (6.00 GDDR5-effective), resulting in memory bandwidth increase to 384 GB/s, up from 320 GB/s. To begin with, the memory amount has been doubled on both cards, to 8 GB. Unlike older, more blatant re-brands, such as GeForce 8800 GT to 9800 GT, AMD did drop in a few changes. Since the Device-IDs are the same, GPU-Z is reading the chip as "Hawaii." The code-name "Grenada" appears in the BIOS version string. This has been confirmed by leaked GPU-Z screenshots, which reveal the device-IDs of the two cards to be identical to those of the R9 290X and R9 290. The 28 nm "Grenada" silicon they are based on, is identical to "Hawaii," down to the last transistor. Its PCB is smaller than even that of the R9 Fury X, and makes do with a slimmer 4+2 phase VRM, than the 6+2 phase VRM found on the R9 Fury X.ĪMD's upcoming Radeon R9 390X and R9 390 performance-segment graphics cards reportedly feature higher GPU and memory clocks over the products they are a re-branding of, the R9 290X and R9 290, respectively. Korean tech blog DGLee posted pictures of an R9 Nano taken apart. The resulting performance is 5-10% higher than the Radeon R9 290X, while never breaching a power target.
So how does it get down to 175W typical board power, from the 275W of the R9 Fury X? It's theorized that AMD could be using an aggressive power/temperature based clock-speed throttle. In terms of clock speeds, the R9 Nano isn't too far behind the R9 Fury X on paper - its core is clocked up to 1000 MHz, with its memory ticking at 500 MHz (512 GB/s). It will feature 4 GB of memory across the chip's 4096-bit HBM interface. Specifications sheet of the R9 Nano leaked to the web, revealing that the card will feature all 4,096 stream processors physically present on the chip, along with 256 TMUs, and 64 ROPs.
The card will feature the full complement of GCN compute units physically present on the "Fiji" silicon, and in terms of specifications, is better loaded than even the R9 Fury. AMD's upcoming mini-ITX friendly graphics card, the Radeon R9 Nano, which boasts of a typical board power of just 175W, is not a heavily stripped-down R9 Fury X, as was expected.
