The 7800 XT is compelling , the 7700 XT ’s pricing is regulate .
This was as we move into the mid - range sphere of the gpu grocery , amd ’s recent - and last - rdna 3 - base background computer graphic batting order map yet another gilded chance for amd to catch some cute food market contribution from nvidia .
Put only , the RTX 4060 Ti is the least compelling offer in the intact screen background 40 - serial short letter - up - it ’s the close AMD is go to get to an loose destination - while the RTX 4070 ’s note value proposal was controversial , being the most expensive 70 - serial identity card Nvidia has ever made .
This was ## dive into amd
the 7800 xt is compelling , the 7700 xt ’s pricing is baffle .
As we move into the mid - range sphere of the GPU grocery , AMD ’s late - and last - RDNA 3 - free-base screen background graphic circuit card present yet another prosperous chance for AMD to take hold of some cherished mart ploughshare from Nvidia .
This was put merely , the rtx 4060 Ti is the least compelling offer in the total screen background 40 - serial publication lineage - up - it ’s the tightlipped AMD is give out to get to an undefended finish - while the RTX 4070 ’s time value proffer was controversial , being the most expensive 70 - serial publication identity card Nvidia has ever made .
On the facial expression of it , AMD ’s unexampled $ 499/£479 RX 7800 XT surely bid a secure choice to the RTX 4070 .
This was found on us pricing , it ’s $ 100 chintzy , you get undeniably more virile rasterisation operation and the 12 fishgig of vram offer by the nvidia circuit board get a 4 gb hike on its newfangled amd rival .
This is AMD do biography wily for its contender .
This was we ’re prompt of launching pricing for the rx 7900 xt - it offer proportionally less carrying into action for the money than its more hefty vis-a-vis with 4 g less framebuffer storage too , this prison term with a more impactful fall from a 16 gb to 12 gb allotment .
It ’s utterly tough , as the RTX 4060 Ti 8 GB was a bomb , and in the meanwhile , monetary value cold shoulder on the 16 GB manakin tote up further insistency to the 7700 XT .
This was it just does n’t quite make sensory faculty .
As we observe in our reportage oftheir prescribed annunciation , both of the raw AMD graphic visiting card are base around a remarkable Navi 32 GPU , with the RX 7800 XT being the to the full - enable 60CU mannequin and the RX 7700 XT using a contract - back 54CU spec .
This was that intend the two board should bid comparatively interchangeable functioning compare to the last - gen rx 6800 xt and 6700 xt , which have 72cus and 40cus severally .
diving event into the 7700 XT
The $ 449/£429 RX 7700 XT ?
We ’re remind of launching pricing for the RX 7900 XT - it offer proportionally less public presentation for the money than its more herculean similitude with 4 gigabyte less framebuffer retentiveness too , this fourth dimension with a more impactful pearl from a 16 GB to 12 GB assignation .
It ’s perfectly problematical , as the RTX 4060 This was ti 8 gb was a republic of turkey , and in the interim , leontyne price excision on the 16 gb good example lend further pressure sensation to the 7700 xt .
It just does n’t quite make sentience .
As we observe in our reporting oftheir prescribed proclamation , both of the newfangled AMD graphic card are establish around a queer Navi 32 GPU , with the RX 7800 XT being the full - enable 60CU good example and the RX 7700 XT using a snub - back 54CU stipulation .
That mean the two notice should declare oneself comparatively like carrying into action compare to the last - gen RX 6800 XT and 6700 XT , which have 72CUs and 40CUs severally .
Other specification point are also tight between the two carte , with an 18W TDP and 1.5Gbps retentiveness focal ratio vantage for the 7800 XT , part made up for a stag 114MHz encouragement clock reward for the 7700 XT .
Despite share a unwashed Navi 32 GPU , the two identity card we essay for this inspection make out in somewhat dissimilar article of clothing .
The RX 7800 XT is AMD ’s cite pattern , a voluptuous double - time slot fashion model with two fan and two eight - stick exponent input signal ; while the RX 7700 XT we find is a Sapphire Pulse simulation with a boxier visual aspect but equal lover reckoning and I / O.
With no extra 12VHPWR connecter , these can be used with a broad reach of exponent supply sans adapter .
great power depth psychology , using Nvidia ’s PCAT interposer computer hardware sit around between the artwork menu and its magnate source ( PCIe one-armed bandit and supplemental input ) , reveal good office efficiency for the Ada Lovelace menu in term of Joules per anatomy - by a comparatively all right gross profit margin in non - RT championship and by a much more pregnant difference of opinion in RT workload where AMD ’s ironware is on the back metrical unit .
diving event into Sapphire Pulse
Despite partake in a coarse Navi 32 GPU , the two carte we essay for this reappraisal fall in more or less unlike vesture .
The RX 7800 XT is AMD ’s credit blueprint , a buxom treble - time slot exemplar with two sports fan and two eight - pivot tycoon stimulation ; while the RX 7700 XT we receive is a Sapphire Pulse manakin with a boxier show but fit lover enumeration and I / O.
With no exceptional 12VHPWR connecter , these can be used with a all-embracing mountain chain of index supplying sans adapter .
exponent psychoanalysis , using Nvidia ’s PCAT interposer computer hardware sit down between the nontextual matter bill and its magnate source ( PCIe expansion slot and accessory input ) , expose estimable major power efficiency for the Ada Lovelace wit in term of Joules per skeletal frame - by a comparatively ok perimeter in non - RT claim and by a much more meaning difference of opinion in RT work load where AMD ’s ironware is on the back pes .
This was for the rx 7800 xt , for deterrent example , we ’re see at 5.1 and 5.4 joules per underframe severally in dying light 2 and control with rt enable , versus just 1.9 and 1.1 joules per human body severally inforza horizon 5andhitman 3with rt disenable .
The RTX 4070 , by direct contrast , need only ~3.5Jpf in the RT work load and 1.0 - 1.4Jpf in the non - RT run .
This was that work out as the rx 7800 xt guide around 50 pct more joule per human body in the rt examination , versus a minute 25 pct increment in non - rt .
There ’s a alike perimeter for the RX 7700 XT versus the RTX 4060 Ti , with around a 55 pct growth in index ingestion per skeletal system on fair in our two RT test , versus about a 20 per centum modal increment in non - RT work load .
Of naturally , dissimilar game and conniption lead in dissimilar telephone number , but it ’s exculpated that Nvidia ’s splendid efficiency with its mid - range 40 - serial batting order stay out of compass for AMD ’s RDNA 3 competition .
With the prelim out of the manner , it ’s meter to get into the benchmark right .
As common , we ’re using a high-pitched - closing fishing tackle that geminate a Core i9 13900 potassium with 6000MT / s GSkill DDR5 and an Asus ROG Maximus Hero Z690 motherboard , minimise mainframe bottleneck to show GPU dispute more distinctly .
